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

Question

please answer this problem doesn't make sense

Answer 1

L=4W

100=LW = 4W(W) = 4W^2

W^2 = 100/4 =25

W = sqr25 = 5

L=4x5 =20

dimensions are 5 x20 inches

Answer 2

Length * width=100

Given length =4 times the width

Or l=4w

4w* w=100

4w^2=100

W^2=100/4

W^2=25

Tasking the square root of both sides

W=5

Therefore w = 5 and l= 4
