Sagot :

Answer:

L = 19 yd

W = 15 yd

Step-by-step explanation:

2L + 2W = 68

L = W + 4

Substitute for L in the first equation

2(W + 4) + 2W = 68

2W + 8 + 2W = 68

4W = 60

W = 15 yd

Plug W in the second equation to find L

L = W + 4

L = 15 + 4

L = 19 yd

Plug both answers in both equations to check

First equation = 2 (19) + 2 (15) = 68

Second equation = 19 = 15 + 4
