The answer is c because you plug in the values given. 4 times .75 is three. Three plus three is 6. For the other side you plug in .50. 6 times .50 is 3. 3-2 is 1. Then you are asked to find the perimeter, a rectangle has 4 sides so you do 6 on the top and bottom and 1 on each of the sides. When you add those all together you get 14 which is c.
