Question

A floor measuring 7 m by 2.8 m is to be covered with tiles measuring 35cm square .How many tiles are needed

Answer 1

Hey mate let's convert all the quantities in cm...

So dimension of floor is 700cm by 280 cm

Area of the floor = 700×280 = 196000 cm^2

Now 1 tile covers 35cm^2 area

So no of tiles needed to cover 196000cm^2 area = 196000/35

= 5600

So total no of tiles used to cover the floor are 5600

HOPE THIS HELP YOU ☺☺
