Question

How many square tiles of side 15 cm will be needed to fit in a square floor of a bathroom of

side 7 1/2 m

Find the cost of tiling at the rate of Rs. 5 per tile

Answer 1

Size of the tile = 15cm

Total length of the floor = 7 1/2m

First of all, lets convert the length to centimeters.

= 7.5 x 100

= 750cm

To find how many tiles needed, divide the length of floor by length of tile.

= 750/15

= 50

So, we will need 50 tiles to fit in the bathroom floor.

To find the price, multiply the number of tiles needed with the cost.

= 50 x 5

= 250 rupees

Answer 2

Step-by-step explanation:

71/2=35.5

area of square= side × side

35.5×35.5

1260.25

no. of square tiles fit in th bathroom = 1260.25/15

=84.01

cost of tiling = 84.01×5

=420.05
