Question

A rectangle is twice as long as it is wide. If the width of the rectangle is 3 inches. What is the rectangle's area, in square inches?

Answer 1

The rectangle is 18 square inches

Explanation:

A rectangle has Length that is twice its Width.
The Width = 3.

What is the area of the rectangle?

First, we know that L, the length, is 6 (twice as long as its width).

Remember that the area of a rectangle is Length times Width:

`A=LW`

and so

`A=6xx3=18`

The rectangle is 18 square inches
