Question

If you know the area and the height of a triangle, how can you find the base.?

Answer 1

2 × Area ÷ height

Explanation:

Area of triangle = ½ × base × height

base = 2 × Area ÷ height

Answer 2

b = 2A/h

Explanation:

The formula for area of a triangle is

A = 1/2 bh where b is the base and h is the height

We want to find the base

Multiply each side by 2

2A = 2*1/2 bh

2A = bh

Divide each side by the height

2A/h = bh/h

2A /h = b

b = 2A/h
