Question

Start with the standard formula for the area of a triangle, and rewrite it to solve for the base, b.

Answer 1

b=2A/h

Explanation:

The formula for area of a triangle is

A = 1/2 bh

Multiply each side by 2

2*1/2 bh = 2A

bh = 2A

Divide each side by h

bh/h = 2A/h

b = 2A/h

Answer 2

2A/h = b

Explanation:

The formula for area of a triangle is

A = 1/2 bh

Multiply each side by 2

2A = 2*1/2 bh

2A = bh

Divide each side by h

2A/h = bh/h

2A/h = b
