Question

A floor 3.0m long and 2.0m wide is to be covered with square shaped tiles of length 10cm. Find the cost of flooring it, of the cost of tiles is rs. 150 per 100 tiles.

Answer 1

First of all we need to find the area

Area of room = Length × breadth
= 3 × 2 = 6m²

Side of one square tile = 10cm

We need to convert it to m
10cm = 10/100 = 0.1 m

Area of one square tile = 0.1 × 0.1 = 0.01m²

Now number of tiles required to flooring it

= Area of room/area of tile

= 6/0.01

= 600 tiles


Cost of 100 tiles = ₹150

So clearly, cost of 1 tile = 150/100

Cost of 600 tiles = 150/100 × 600

= ₹900

Hope it helps dear friend ☺️✌️
