Answer 2

Given :

• Dimensions of the floor of a room are 5 m and 3 m which are to be covered with square tiles.
• Side of each square tile = 25 cm

To Find :

• The number of tiles required.

Solution :

Firstly, we need to convert the dimensions into cm unit. As we know that, 1 m = 100 cm so let's find out for 5 m and 3 m.

$\implies \: \tt \: 5 \: m = 5 \times 100 \\ \implies \bf \: 500 \: cm$

$\implies \: \tt \: 3 \: m = 3 \times 100 \\ \implies \bf \: 300 \: cm$

∴ Dimensions of the floor of a room are 500 cm and 300 cm.

Now, multiplying both the dimensions of room..!

$\implies \tt \: 500 \: cm \times 300 \: cm \\ \implies \bf \: 150000 \: cm^2$

Now, as per the provided informations. It is given that, area of each square tile is 25 cm. So basically, we need to apply formula of area of square (side × side) and multiply both the sides..!

$\implies \tt \: 25 \: cm \times 25 \: cm \\ \implies \bf \: 625 \: cm^2$

Now, lastly we need to divide the value of dimensions of floor with the area of square tile.

$\implies \tt \: \cancel\dfrac{150000}{625} \\ \\ \implies \: \underline{ \boxed{ \bf{240}}} {\pink{ \sf_{(No. \: of \: tiles \: required)}}}$

∴ The total number of tiles required is 240 tiles respectively.
