Answer:
W = 10
L = 20
Step-by-step explanation:
2L + 2W = 60
L = 2W
Substitute for L in the first equation
2(2W) + 2W = 60
4W + 2W = 60
6W = 60
W = 10
Plug in W in the first equation
2L + 2(10) = 60
2L + 20 = 60
2L = 40
L = 20
Plug both answers in both equations to check
2(20) + 2(10) = 60
20 = 2 * 10
Hope that helps!
