The length of a rectangle is 2 inches less than twice its width. the area of the rectangles is 40 square inches find the length and width.

Lenght (L)

Width(W)

L = 2W -2

Peremeter (P) = 2L + 2W

40 = 2(2W-2) + 2W

40 = 4W - 4 + 2W

40 = 6W - 2

6W = 42

W = 42/6

W = 7 in

in eq1 L = 2W-2

L = 2(7) - 2

L = 14 - 2

L = 12 in

L=3W

P=96cm

P=2(L+W)

96=2(3w+W)

96=2*4W

96=8W

8W=96

W=96/8

W=12cm

L=3W=3*12

L=36cm
