Respuesta :
P = 2(L + W)
P = 126
L = 2W
126 = 2(2W + W)
126 = 2(3W)
126 = 6W
126/6 = W
21 = W
L = 2W
L = 2(21)
L = 42
so the length (L) = 42 ft and the width (W) = 21 ft
P = 126
L = 2W
126 = 2(2W + W)
126 = 2(3W)
126 = 6W
126/6 = W
21 = W
L = 2W
L = 2(21)
L = 42
so the length (L) = 42 ft and the width (W) = 21 ft
