Answer 2

SOLUTION:-

Given:

•The length & breadth of a rectangular floor are 12m & 8m.

To find:

The tiles of square shape with each side 40cm are required to pave the floor.

Explanation:

We have,

• Length of the rectangular floor= 12m
• Breadth of the rectangular floor=8m

Area of the rectangular floor:

Area= [Length × Breadth]

Area= [12m × 8m]

Area= [ 96]m²

&

Tiles of the square shape with each side= 40cm.

We convert in metre

1cm= 1/100m

40cm = 40/100m

=) 0.4m

Area of the tiles= Side × Side

Area of the tiles= 0.4m × 0.4m

Area of the tiles= 0.16m²

Now,

Number of tiles:

$= > \frac{Area \: of \: the \: rectangular \: floor}{Area \: of \: the \: tiles} \\ \\ Number \: of \: tiles = \frac{96 \times 100}{0.16 \times 100} \\ \\ Number \: of \: tiles = \frac{9600}{16} \\ \\ Number \: of \: tiles = 600$

Thus,

The number of tiles required is 600.
