You have to use your area equations.like basex height
I believe the equation should be set up like this: 85 + 5x + 5x + 5x - 10 + 5x + 5 = 540. Don't forget to combine like terms! Please let me know by sending me a message if you need any more help :)
Answer:
x = 12, y=7
x=30, y=25
x=15, y=10
Step-by-step explanation:
We have : y = x - 5
x = 12 then y = 7, y = 12 - 5 = 7
x = 30 25 = x - 5, x = 25 + 5 = 30
x = 15, y = 15 - 5 = 10, y = 10
