Question

A room is 13.6 m long and 6.4 m wide it is to be paved with square marble tiles each of side 80 cm . how many marble tiles will be required

Answer 1

Answer:

136

Step-by-step explanation:

area of room =l* b

(13.6*6.4)m2

or

(1360*640)cm2

area of tile =80cm

area of tile=side *side

(80*80)cm2

number of tiles required =1360*640/80*80

=136

Answer 2

Solution:

First find the area of the floor.

Area of the floor
= l • w
= 13.6 x 6.4 = 87.04 m^2

Next find the area of a tile

Area of the square tile
= 80 cm ——> convert to meter
= 0.8 m
= 0.8^2
= 0.64 m^2

Tiles required
= 87.04 / 0.64
= 8704 / 64
= 136

Therefore, 136 tiles will be required.

Hope this would help.
