For this case we have that by definition, the perimeter of the rectangle is given by:

Where:
W: Is the width of the rectangle
L: is the length of the rectangle
According to the data we have:

Substituting:

So, the width of the rectangle is 9 inches

So, the length of the rectangle is 15 inches

Answer:
15
Step-by-step explanation:
a^2 + b^2 = c^2
20^2 +b^2 = 25^2
400 + b^2 = 625
-400           -400
b^2 = 225
b = √225
b = 15
