HELP!

The length of a rectangle is 4 times its width. The rectangle’s width is 8 m.

What is the area of the rectangle?


Enter your answer in the box.

Respuesta :

Lets width be x
Length 4 times width = 4x
Area of rectangle = l . w
                             = 4x . x
                              = 4x^2
Plug in x- value :   = 4(8)^2
                               = 256m ^2

correct the answer is 256. I just finished the test and it was correct.
