Question

The area of a square shaped hall is 56.25 m^2 .if tiles measuring 15cm*15cm are laid on the floor, find the number of tiles used?​

Answer 1

Answer:

The area of a square-shaped hall is 56.25 sq. m. If tiles measuring 15cm × 15cm are laid on the floor, then the number of tiles used is 2500 tiles.

Step-by-step explanation:

Given: The area of a square-shaped hall = 56.25 sq. m

Length of tiles = 15cm

And the breadth of tiles = 15cm

Find the number of tiles used.

The area of a square-shaped hall = 56.25 sq. m

Find the area of tiles

The area of tile = length × breadth

= 15 × 15

= 225 sq. cm

If 100 cm = 1 m

So, 10000 sq. cm = 1 sq. m

So, the area of the tile in sq. m is 0.0225 sq. m.

The number of tiles used = The area of a square-shaped hall  ÷ area of tile

= 56.25 ÷ 0.0225

= 2500 tiles

So, 2500 tiles are required for the flooring hall.
