Question

A room 24 m long and 18 m wide is to be paved by square marble tiles each of side 80
cm. How many such marble tiles will be required?​

Answer 1

Answer:

675

Step-by-step explanation:

Area of the room = 24 × 18

= 432 sq.m

Area of a tile = 80 × 80 × 10^-4

= 6400×10^-4 sq. m

n × area of a tile = area of room

n × 64 × 10^-2 = 432

n = 432 × 10^2 ÷ 64

n = 675

Therefore, 675 such marble tiles required.
