feet

If you would like to know what is the area in square feet including the additional amount, you can calculate this using the following steps:

12 1/2 feet long * 11 feet wide = 25/2 feet * 11 feet = 137.5 square feet

10% of 137.5 square feet = 10% * 137.5 = 10/100 * 137.5 = 13.75 square feet

137.5 + 13.75 = 151.25 square feet

The correct result would be 151.25 square feet.
