A certain figure shows a modern painting that consists of four differently colored rectangles, each of which has length 'l' and width 'w'. If the area of the painting is 4,800 square inches, what is the width, in inches, of each of the four rectangles?
A.)15
B.)20
C.)25
D.)30
E.)40
Here is the picture of it from the book. I don't know how 'l' = 3w
I have an answer to this and it involves the explanation that 'l' = 3w and plugging it in the equation l(w+l). How does one get 'l' = 3w? P.S. it's number 73.
