The altitude of an equilateral triangle is 15. What is the area of the triangle?

The altitude of an equilateral triangle is 15.

In order for us to get the area of the equilateral triangle, we need to find the formula first.

Area = square root of (3) / 4 * a^2

Area = square root of (3) / 4 * 15^2

Area = 97.42786 square units.

So the area of the equilateral triangle given the altitude 15 is 97.43 square units.
