Question

Justin is redoing his bathroom floor with tiles measuring 6in by 13 in. the floor has an area of 8,500 in². what is the least number of tiles he will need?

Answer 1

He will need 109 tiles

Answer 2

Each tile is 6 in. by 13 in.....so the area of each tile is L * W = 6 * 13 = 78 in^2

the entire floor has an area of 8500 in^2

so the least number of tiles needed is : 8500/78 = 108.97.....109 tiles are needed
