Solution:
A rectangular floor with the dimensions of 8 meters by 10 meters needs to be covered by carpet squares. Each carpet square measures 2 meters by 2 meters and costs $12 per square. We must determine the total cost to cover the floor in carpet squares. Let’s start by determining the area of the floor and the area of each carpet square.
Area of floor = 8 x 10 = 80
Area of each carpet square = 2 x 2 = 4
Thus, the total number of carpet squares needed to cover the floor = 80/4 = 20 carpet squares.
Since the cost of each carpet square is $12, the total cost for 20 carpet squares = 20 x $12 = $240
