An area of a garden needs to be tiled. It consists of a square area of 10m by 10m, with an outdoor pool in the middle of radius 3m. The tiles to be used are 50cm by 50cm, and cost 50p per tile. Find out how much it will cost to tile the area.

Calculate total area of space: A = 10 10 = 100m 2 Calculate area of pool: A = Pi r 2 = 3.142 3 2 = 28.27m 2 Difference in area = 100m 2 - 28.27m 2 = 71.73m 2 Calculate area of one tile: A = 0.5 0.5 = 0.25m 2...
