Question

A room is 13.6m long 6.4 m wide. its floor has to be paved with square marbles tiles of side 80 cm . how many tiles will be required solution​

Answer 1

Step-by-step explanation:

Area of room = 13.6 * 6.4 = …87.04 m^2

Size of tile = 0.8 m

Area of tile = 0.8 * 0.8 = 0.64 m^2

No.of tilez required = 87.04/.64 = 136

Answer 2

Answer:

Area of the room = length×breadth

=13.6m×6.4m

=87.04m square

Area of each square tile = side×side

=80cm

the area of room is in metre so let's convert 80cm to m

= 0.8m

= 0.8m×0.8m

= 0.64m square

Step-by-step explanation:

No.of tiles needed = 87.04/0.64

=136

136 tiles are needed to pave the room
