Question

A rectangle is twice as long as it is wide. If it has an area of 84.5 square inches, what are its dimensions?

Enter them below, separated by a comma.

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 = L W

and so

A = 6 × 3 = 18

The rectangle is 18 square inches
