I want to pave my patio, which has dimensions of 6m by 8m. I'm going to pave it with stones that have dimensions of 50cm by 50cm. Each tile costs £1.50. How much will paving my patio cost me?

My patio has an area of 68 m , so 48m².
Each tile has an area of 0.50.5 m, so 0.25m².
To find the number of tiles we need, we divide the area of the patio by the area of one tile:

48/0.25 = 192 tiles

Each tile costs £1.50, so the overall cost in pounds is:

192*1.50 = £288.00
