Question 282715
Hello, 
Let the width be x and the length will be 4x-5. Now we can set up our equation as:
x+x+(4x-5)+(4x-5)=40 Combine like terms to get:
10x-10=40 Add 10 to both sides and divide by 10 to get:
x=5
There we go the width is 5 inches. I'll let you figure out the width. 
(Note: Lenegth is spelled length and fourty is spelled forty)
