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

The answer is A

Answer:

4.32

You can multiply 16 by 0.27 to get the answer.

You can check your work with estimation because 27% is about 1/4 of the number, and just by looking at the number, 4 is 1/4 of the number.
