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.

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

It’s hard to understand what you put.. can you show a picture ?
