Question

A pool covers costs about $17.50 per square meter. Calculate the cost of covering the Children's pool.

Answer 1

First calculate the area of the pool, which is 15 x 15, = 225 sq meter, 
and just multiply the cost for each sq meter by the area, 
17.5 x 225
therefore the cost will be $3937.5

Answer 2

In order to answer your question, you must find the area of the children's pool. Since it is mentioned that the pool's shape is a square and has a side of 15m, you have to find the area of the square, which is s^2. 15m^2 is equal to 225 square meters. Since one square meter costs $17.50, the total cost of covering the pool is 17.50*225, which equals to $3937.50.
