Answer:
Step-by-step explanation:
I'm going to assume it is a rectangle.
P = 2L + 2w = 34
Area = L * w = 60 Divide by L
w = 60/L Substitute into the perimeter.
P = 2L + 2w = 34 Put (60/L) for w
P = 2L + 2(60)/L = 34 Multiply both sides by L
P = 2L^2 + 120 = 34L Subtract 34L from both sides.
2L^2 - 34L + 120 = 0 Divide everything by 2
L^2 - 17L + 60 = 0 Factor
(L - 5)(L - 12) = 0
Since L is usually the larger value, use L = 12
L*w = 60
12w = 60
w = 60/12
w = 5
