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.
13 divided by 11.3 is 1.150442477876106. So 15 by 1.150442477876106 and you get 13.03846162772485. Just round it to the nearest tenth and you get 13.0.
