Question

He area of the picture is 100 square inches. The length is 4 times the width. Find the length and width of the picture.

A rectangular image of a chameleon.

The length of the picture is
inches.

The width of the picture is
inches.

Answer 1

Length * width=100Given length =4 times the width Or l=4w4w* w=1004w^2=100W^2=100/4W^2=25Tasking the square root of both sides W=5Therefore w = 5 and l= 4

Explanation:

Answer 2

length = 4w=4×5=20

width=w= 5

Explanation:

length = 4w

width=w

area=length × width = 4w×w= 100

=4w^2 =100

w^2 =100/4=25

w = √25

w=5

length = 4w=4×5=20

width=w= 5
