What are the length and width of the rectangle?

Question

The area of the rectangle is 27 square feet. The rectangle is 3 times longer than it is wide.

Answer 1

Let x be the width of the rectangle, then

(3x)(x)=27

x=3

so length is 9feet, width is 3feet

Answer 2

Hi Sydney,

The area of the rectangle is 27 square feet. The rectangle is 3 times longer than it is wide.

Area= Length * Width

The area of the rectangle is 27 square feet

Area= 27

The rectangle is 3 times longer than it is wide.

Length=3x

Width=x

Area= Length*Width

27=3x*x

27=3x²

/3 /3

9=x²

√9=√x²

3=x

Width =3

Length=3(3)=9

Check

A=LW

9*3=27
