Answer:
The cost of tiling per square meter is $12.50
Step-by-step explanation:
first find the area of the pool - 31 2/3 x 7 1/5 = 228 m squared.
then find 25% of the total area because 25% of the area is the size of the tiles arount the pool. 25% of 228 = 57 m squared.
then do 712.50 divided by 57 to find the amount of money for one square meter. 712.50 / 57 = $12.50
