Question

A triangle with dimensions, height, h, and base, b, is shown below. The area is 75 ft2. Calculate the height of the triangle.

Answer 1

While we cannot see the triangle we can assume you are given some other dimension information. You know that the area of a triangle is 1/2 b*h, so you have \[\frac{1}{2} b \times h = 75\] and you want to know what b is. Simply use algebra to move everything away from b and then solve.
