A dance studio wants to use square mirror tiles to cover two walls in their studio that measure 2 feet by 2 feet. Each wall measures 9 feet tall by 22 feet long. The studio instructor has requested that a 1 foot gap be left between the floor and the start of the mirrors. How many mirror tiles are needed to cover both walls?

Since one foot on the bottom will not be covered we need to cover a wall that is 8 feet tall by 22 feet long.
A = bh or area = 8 x 22 = 176 square feet.

Each tile is 2 x 2 or 4 ft ²
So the question becomes, "How many 4ft² tiles do we need to cover 176 ft²"?

176 ÷ 4 = 44 tiles

Size of each tiles = (2*2) square inch
= 4 square inch
Since 1 inch gap needs to be kept with the floor, so the height of floor that needs to be covered with square mirror tiles is 8 inch.
Size of each wall = (8*22) square inch
= 176 square inch
So the number of mirror tiles required per wall = 176/4 tiles
= 44 tiles
Number of tiles required to cover both walls = (44*2) tiles
= 88 tiles.
