Answer:

The perimeter is 35.6 meters

Explanation:

The pool measures 8m by 5m. The tiles surrounding the pool add 2.4 m to each edge. That is added to the original dimension, which makes the outside dimensions 10.4 m by 7.4 m.

The perimeter of a rectangle is the sum of all its sides:

2*(10.4m) + 2*(7.4 m)

20.8 m + 14.8 m

Perimeter = 35.6 m
