Answer 1

Answer:

GIVEN

We are given the dimensions of a room and also the dimensions of square marble tiles

TO FIND

Number of tiles required to pave the room

SOLUTION

To find the number of tiles , first we need to find the area of the room and the area of a single tile

Length of room = 680 cm

Breadth of room = 320 cm

Side of square tile = 40cm

Area of room = length × breadth

Area = 680 × 320 cm^2

Area of one tile = side × side

Area = 40 × 40 cm^2

Total number of tiles = Area of room / Area of one tile

Number of tiles = 136 tiles
