Answer:
W = 17
L = 40
Step-by-step explanation:
To find the perimiter, we add 2L + 2W
So: 2L + 2W = 114
We also know that: L - 6 = 2W
So we can plug in L - 6 into the original equation
2L + L - 6 = 114
Add 6 to both sides
3L = 120
L = 40
Now we can solve for width using any of our equations. I'll use L - 6, because it's the easiest
L - 6 = 2W
40 - 6 = 2W
34 = 2W
17 = W
So
W = 17
L = 40
