how many square 2''x2'' will cover an area that is 10ft x 20ft

To find out how many square tiles measuring 2''x2'' would cover an area of 10ft x 20ft, we need to convert the measurements to a consistent unit.

First, let's convert the 10ft x 20ft area into inches since the tile measurements are given in inches.

10 feet is equal to 10 x 12 = 120 inches.
20 feet is equal to 20 x 12 = 240 inches.

Now we have the area in inches: 120 inches x 240 inches.

Next, let's calculate the area of one tile. Since each tile measures 2''x2'', the area of one tile is 2 inches x 2 inches = 4 square inches.

To determine how many tiles are needed to cover the entire area, divide the total area by the area of one tile:

(120 inches x 240 inches) ÷ 4 square inches = 28,800 square inches ÷ 4 square inches = 7,200 tiles.

Therefore, you would need 7,200 square tiles measuring 2''x2'' to cover an area that is 10ft x 20ft.
