Question

A triangle has an area of 54 m² and a height of 9 m.

How long is the base of the triangle?

Enter your answer in the box.

Answer 1

base = 3

Explanation:

The area of triangle is calculated using the following formula:

1/2*b*h (b: base, h: height)

The area and height is given, to find the base we can make the following equation:

1/2*b*9 = 54

9b/2 = 54 multiply both sides by 2

9b = 27 divide both sides by 9

b = 3
