Question

A room is 13.6 meters long and 6.4 meters wide. Its floor has to be paved with square marble tiles of side 80 cm. How many tiles will be required?

Answer 1

Answer:

Step-by-step explanation:

First of all we have to find the area of the room.

Area of the room (which is rectangle) = l x b

= 13.6 x 6.4

= 87.04m²

Side length of marble tile = 80cm

= 80/100

= 0.8 x 0.8

= 0.64

Tiles: 87.04/0.64

= 136

Answer 2

• We have to evaluate the above expression by using the given data.

           Given data:-  A room is$13.6$ meters long and$6.4$ meters wide.

           To find:-Value of how many tiles will be required.

           Solution:-

            Therefore we get,

           $\text { Area pavement }=13.6 \times 6.4=87.04 \mathrm{~m}^{2}$

          $\text { Area of } 1 \text { marble tile (square shaped) }=(80)^{2}$

                                                                       $=6400 \mathrm{~cm}^{2}\\=0.64 \mathrm{~m}^{2}$

        $\text { Number of tiles }=\frac{\text { Area of pavement }}{\text { Area of } 1 \text { tile }}$

                                   $=\frac{87.04}{0.64}=136$

        Hence we will require the$136$ tiles.
