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?

Respuesta :

Answer:

200 tiles

Step-by-step 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
