Question

The formula for the area of a triangle is A = 12bh, where b is the base of the triangle and h is the height of the triangle. What is the length of the base if the area is 32 cm2 and the height is 4 cm?

Answer 1

The base is 16 cm long.

Explanation:

A = 1/2 * bh, we know that A = 32 and h = 4. We are solving for b so we can plug A = 32 and h = 4 into the equation to solve for b.

A = 1/2 * bh

32 = 1/2 * b * 4

32 = 2b

b = 16cm
