Question

5. A floor 15 m long and 12 m broad is to
be paved with square tiles of side 30 cm.
Find the number of tiles required.​

Answer 1

Answer:

area of floor=lxb=15×12=180m²

area of one tile = sxs=30x30=900cm²=0.09m²

no. of tiles required= area of floor/area of tile

=180/0.09=2000

Answer 2

The number of tiles required is 2000.

Explanation:

Given : Length of floor = 15 m = 1500 cm [∵ 1 m = 100 cm]

Width of floor = 12m = 12 00 cm

Then Area of the floor =Length of floor x Width of floor

1500 x 1200 =1800000 sq. m

Side-length of the square tile = 30 cm

Area of  square tile = (side)²

= (30)² = 900 sq.cm

Number of tiles required. = (Area of the floor )÷(Area of  square tile )

(1800000 ) ÷ (900)= 2000

Hence, the number of tiles required is 2000.
