Question

The length of a rectangle is 3 times the width. The area of this rectangle is 243 feet squared.

What are the dimensions?
Width =____feet (this is the short side)
Length=____feet (this is the long side that is 3 times the width)

Answer 1

Explanation:

width = x

length= 3x

Area = length * width

243=3x * x

3÷243 =3x^2÷3

√81=√x^2

x=9

3x=3*9=27

Width=9

Length=27
