There are many different shapes and many reasons why you might want to know their area!

Find the area of the following

The following are calculators to evaluate the area of seven common shapes. The area of more complex shapes can usually be obtained by breaking them down into their aggregating simple shapes, and totaling their areas. This calculator is especially useful for estimating land area. Use the Triangle Calculator to determine all three edges of the triangle given other parameters. Area is a quantity that describes the size or extent of a two-dimensional figure or shape in a plane. It can be visualized as the amount of paint that would be necessary to cover a surface, and is the two-dimensional counterpart of the one-dimensional length of a curve, and three-dimensional volume of a solid. Provided below are equations for some of the most common simple shapes, and examples of how the area of each is calculated. A rectangle is a quadrilateral with four right angles. It is one of the simplest shapes, and calculating its area only requires that its length and width are known or can be measured. A quadrilateral by definition is a polygon that has four edges and vertices. In the case of a rectangle, the length typically refers to the longer two edges of the quadrilateral, while the width refers to the shorter of the two edges. When the length and width of a rectangle are equal, the shape is a special case of a rectangle, called a square. The equation for calculating the area of a rectangle is as follows:.

What would be area of the front side? Multiply the radius times itself. Method 4.

.

This triangle area calculator can help in determining the triangle area. The basic triangle area formula needs to have a base and height given, but what if we don't have it? How can we calculate the area of a triangle with 3 sides only? The triangle area calculator is here for you. Give it a go! If you are still unsure how to find the area of a triangle, check the description below. A triangle is one of the most basic shapes in geometry. The best known and the most straightforward formula, which almost everybody remembers from school, is:.

Find the area of the following

This area of a regular polygon calculator can help — as you can guess — in determining the area of a regular polygon. Type the number of sides, along with a known property, and the polygon area will appear in no time. If you're wondering how to find the area of a polygon or what is the area of a polygon formula, keep reading. If you want to calculate the area of any 3-sided or 4-sided polygon, check out the triangle area calculator and the quadrilateral area calculator. The most popular, and usually the most useful formula is the one that uses the number of sides n n n and the side length a a a :. If you want to find the area of a regular polygon, simply use the formulas described above. However, if the polygon is not regular which means it isn't equiangular and equilateral , you can:. Determine the polygon area given side lengths and some diagonals by splitting the polygon into triangles. Then find the area with the given three sides SSS equation you can learn the origin of this formula with our Heron's formula calculator.

In this first tutorial we learn the method for finding the area enclosed between two curves using integration. The base and top are the two parallel sides, while the height will be taken on one of the sides with the angle. Instead of length and width however, a parallelogram uses base and height, where the height is the length of the perpendicular between a pair of bases. Rated this article:. As the farmer has now become more comfortable with SI, he is able to be more creative with his use of units, and can build a more reasonably sized ramp while adhering to his daughter's demands. That gives us a value of The three-step method we've just seen is summarized here make a note of it. Multiply the two radii. Please log in with your username or email to continue. Break the shape down into sections. How to. The resulting number after you multiply the height is the area of the trapezoid. More reader stories Hide reader stories. Italiano: Calcolare l'Area di una Figura Geometrica. Radius r.

The following are calculators to evaluate the area of seven common shapes. The area of more complex shapes can usually be obtained by breaking them down into their aggregating simple shapes, and totaling their areas. This calculator is especially useful for estimating land area.

Using this information:. To find the area of a circle, start by measuring the distance between the middle of the circle to the edge, which will give you the radius. Measure the width and height. Thanks Helpful 1 Not Helpful 2. You can also find this by taking the diameter, or the measurement of the width of the circle, and dividing it in half. It can be visualized as the amount of paint that would be necessary to cover a surface, and is the two-dimensional counterpart of the one-dimensional length of a curve, and three-dimensional volume of a solid. Co-authors: Get help from a friend if you're having a hard time! As mentioned in the calculator above, please use the Triangle Calculator for further details and equations for calculating the area of a triangle, as well as determining the sides of a triangle using whatever information is available. Unfortunately for the farmer's daughter, she grew up in an environment brimming with positive reinforcement, and subsequently, the mentality that one should "shoot for the moon [since] even if you miss, you'll land among the stars," as well as the assertion from everyone around her that she could do absolutely anything she put her mind to!
