A rectangular patio has a perimeter of 60 feet. if the length of the patio is 3 feet less than twice the width, find the dimensions of the patio.

P = 2 (L + W)

P = 60

L = 2W - 3

60 = 2 (2W - 3 + W)

60 = 2 (3W - 3)

60 = 6W - 6

60 + 6 = 6W

66 = 6W

66/6 = W

11 = W < = = = the width is 11 ft

L = 2W - 3

L = 2 (11) - 3

L = 22 - 3

L = 19 < = = = the length is 19 ft
