Question

The formula for the area of a triangle is A= 1/2 bh, 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 22cm? and the height is 8 cm?

Answer 1

The length of the base = 5.5cm.

Explanation:

A = 1/2 bh

A = 22cm^2 h = 8cm.

22 = 1/2 b(8)

22 = 4b

hence b = 5.5cm.
