Enter them below, separated by a comma.

Answer 1

Answer:

The rectangle is 18 square inches

Step-by-step 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
