So you wont forget what you wrote and it helps you to figure out the problem. I hope this helps.
Is 1/2 an answer? That’s what I keep getting
Answer: 2/15
Explanation: 2/9 x 3/5 then simplify it
The width would be x-4 and
Length would be x
Add all of the sides together
(x-4)+(x-4) + x + x =72,
Which would come out
4x-8=72
Subtract 8 fro, 72 and you get 64
Then divided 64 by 4
So. Width is 16 and length is 20 . given (x-4)
