Question

A triangle with a base of 6cm has an area of 30cm squared. What is its perpendicular height?

Answer 1

The area of a triangle is 1/2bh. We know the area, a, the base, b, and we are attempting to find the height, h. So, we simplify the area formula with the value of b and solve for h, given a.

1/2(6)h = 30
3h = 30

Isolate h.

3h/3 = 30/3
h = 10
