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.

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

square root of 3

Step-by-step explanation:

fractions no matter what they are are always rational and the square root of 4 is 2 so the only one it could be is the square root of 3.
