The answer is A) 4 inches
how?: knowing that rectangle are parallels to its opposite side and the length is 1 ft which is 12 inches, adding both side you get 24 inches which you would have to subtract from your original 32 inches which would be 8 inches remaining. now dividing that by 2 because you still have two more side and they should be equal you get 4 inches on both side.
