Question

mr.ross is building playroom.he is going to tile the flooring using 20cmx20cm tiles. the floor measures 2mx4m in area. how many tiles will he need to complete the job?

Answer 1

200 tiles

Explanation:

First convert meters to centimeters:

2 m = 200 cm and 4 m = 400 cm

Get the area of the floor:

Area 1: 200 x 400 = 80,000 cm

Get the area of the tile:

Area 2: 20 x 20 = 400 cm

Then, we divide area of the floor by area of the tile:

x = Area 1 / Area 2

x = 80,000/400

x = 200 tiles
