Question

A room is 8.60m long and 6.25m wide. Its floor is to
be covered with the designer
tiles of size 20cm x 10cm.
Find the total cost of tiles if
the cost of one tile is Rs. 100. step by step​

Answer 1

Answer:

Step-by-step explanation:

First let's find area of the floor.

For area of floor,

Length = 8.60m, breadth = 6.25m, The floor is rectangular.

Therefore, area of rectangle = L x B

= 8.60x 6.25

= 53.75

Therefore, area of the floor is 53.75sq.m.

Now we'll find area of the tile

For area of tile,

length = 20cm, breadth = 10cm, Tile is rectangular.

Therefore, area of rectangle = L x B

= 20 x 10

= 200

Therefore, area of the tile is 200sq.cm

Conversion of meter to cm

1 m = 100cm

53.75m = 53.75 x 100

= 5375cm

Now, to determine the no. of tiles needed

= Area of floor / area of tile

= 5375/200

= 53.75/2

= 26.845

Therefore, approximately 27 tiles are needed.

Cost of one tile = 100rs.

Cost of 27 tiles = 27 x 100

= 2700

Therefore, the total cost of tiles will be rs.2700 (APPROX).
