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=(1)/(2)(b* h)`

Substitute the given values in the above expression.

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

Thus, the base of the triangle is 10 ft.
