Find area of triangle with 3 sides calculator

Let us learn how to find the area of triangle with 3 sides given; that is when the length of three sides of a triangle is given.

The 3 sides triangle area calculator is here to the rescue if you need to calculate the area of a triangle but only know the three side lengths. A good example is trying to figure out the area of a triangular-shaped room — with this calculator, you'll learn how to find the square footage of a triangle room. To calculate the area of a triangle using the three side lengths is surprisingly tricky. If we know the height , then the area is found by simply multiplying the height by the base length and dividing by two. What we have built is a triangle area calculator — 3 sides and without height. It's believed Archimedes knew the formula years earlier, but it was never published at the time, as far as we know.
