The length of a rectangle is four times the width. The
perimeter of the rectangle is 40 inches. What is the area of
the rectangle (in square inches)?

Respuesta :

Answer:

Step-by-step explanation:

let the width=x

length=4x

P=2(l+w)=2(4x+x)=10x

10x=40

x=40/10=4

width=4 in

length=4×4=16 in

area=16×4=64 square inches.
