Question

A hall measures 16m by 12m.how many square tiles of side 25cm will be required to pave its floor? how to do these type of problem sums

Answer 1

First find the area of the hall

16 × 12 = 192 m²

Find the area of a single tile in the same unit of area of the hall.

0.25 × 0.25 = 0.0625 m²

Divide hall area by single tile area

192/0.0625 = 3072 tile.

You will get the answer.

Answer 2

Given: A hall measures 16m by 12m.

To find: How many square tiles of side 25 cm will be required to pave its floor.

Solution:

First, the area of the floor of the hall must be calculated. The hall is a cuboid so the floor is a rectangle.

$Area = l*b$

        $= 16 * 12$

        $= 192 m^{2}$

The length of the side of the square is 25 cm which is 0.25 m in length. Now, the area of the tiles is calculated as follows.

$area = 0.25 *0.25$

       $= 0.0625 m^{2}$

Thus, the number of tiles required to pave the floor is calculated as shown below.

$\frac{192}{0.625} = 313.6$

Therefore, 313.6 square tiles of side 25 cm will be required to pave its floor.
