Then, you would multiply the 74 ft by the $15. Shelly has to pay $1,110 to put a child safety fence around the edge of her swimming pool.

$1,110

Step-by-step explanation:

First, find the perimeter of this trapezoidal shape.

Here the perimeter is the sum of 16 ft, 25 ft, 16 ft and 17 ft, which

comes out to 74 ft.

Since the unit cost of the fence is $15/ft, the total that this person must pay for the fence is

($15/ft)(74 ft) = $1,110
