1. Find an expression for the perimeter:

The perimeter of any 2-d, closed shape is the total of all of the side lengths added up.

That is b + c + b - 2 + c - b, which is equal to b + 2c - 2.

2. Find perimeter when b = 11 and c = 16

Simply plug in the numbers to our new expression.

11 + 2(16) - 2, which is 41 inches.
