Question

A sail in the shape of a triangle has an area of 60 square feet. The height of the sail is 12 feet. Find the base of the sail.

Answer 1

Given data:

The area of the triangle is A=60 square feet.

The height of the triangle is h=12 feet.

The expression for the area of the triangle is,

$A=\frac{1}{2}(b\times h)$

Substitute the given values in the above expression.

$\begin{gathered} 60\text{ square-ft=}\frac{1}{2}b(12\text{ ft)} \\ b=10\text{ ft} \end{gathered}$

Thus, the base of the triangle is 10 ft.
