Step-by-step explanation:
this is the same concept basically as simplifying 
into 
. You can see that the denominator is in front of the radical and that any numbers in the numerator are the power of the number underneath.
Let the width be x
The length would be 2x-5
So, 2(x+2x-5)=80
3x-5=40
3x=45
x=15.
So the width is 15 and the length would be 25.
Answer:
