A 12ft by 15ft rectangular swimming pool has a 3ft wide no slip surface around it. What is the outer perimeter of the no-slip surface? . A- 78ft. B-78ft^2. C-198ft. D-198ft^2
First you add 3 twice to both sides of the swimming pool
12 + 6 = 18
15 + 6 = 21
The perimeter is the sum of all sides therefore
18 + 18 + 21 + 21 = 78
