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
Hope that helps!
