Question

A triangular piece of fabric has an area of 45 square inches. The height of the triangle is 15 inches. What is the length of the triangle’s base?

Answer 1

The length of the triangle’s base is of 6 inches.

Explanation:

The area of a triangle is given by the following equation:

`A = (b*h)/(2)`

In which b is the length of the triangle's base and h is the height.

In this question, we have that:

`A = 45, h = 15`

So

`A = (b*h)/(2)`

`45= (15b)/(2)`

`15b = 45*2`

`b = (45*2)/(15)`

`b = 6`

Area in square inches, the length of the triangle's base will be in inches.

The length of the triangle’s base is of 6 inches.
