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

Answer:

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

Step-by-step explanation:

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

$A = \frac{b*h}{2}$

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

$A = \frac{b*h}{2}$

$45= \frac{15b}{2}$

$15b = 45*2$

$b = \frac{45*2}{15}$

$b = 6$

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.
