Here, the question has given us the side of a square room that is 10m. We have to do flooring of that square room and find the cost of flooring. The length and breadth of the tile is given that is 25cm × 20cm. So, to find the cost of flooring we need to first find the area of the room. Then after as the room side is given in metre we need to convert metre in centimetres. After it we need to find the tiles required and at last we have to multiply the cost of 1 tile by the no. of tiles required. The digits we will get after multiplying will be the cost required in flooring.

ANSWER:-

  • Cost of the required tiles is Rs 15,000.

GIVEN:-

➜ Side of the square is = 10 m

➜ Size of marble tile is = 25 cm × 20 cm

➜ Rate of 1 tile = Rs 7.50

TO FIND:-

➜ Cost of flooring = ?

SOLVING STEP BY STEP:-

  • First we will find the area of the room.

➜ Area of room = Side × Side

➜ Area of room = 10 m × 10 m

➜ Area of the room = 100m²

➜ So, area of the room is 100m².

➜ Length = 25 cm = 0.25 m (To convert in M = 1/100)

➜ Breadth = 20 cm = 0.20 (To convert in M = 1/100)

➜ Area of a tile = Length × Breadth

➜ Area = 0.25 m × 0.20 m

➜ Area = 0.25 m × 0.20 m = 0.05 m²

➜ Area = 0.05 m²

  • No. of tiles required for the flooring = Area of room / Area of tile

➜ Tiles required = 100m² / 0.05m²

➜ Tiles required = 100m² / 0.05m² = 2,000

➜ Tiles required = 2,000 Tiles

  • Cost of the tiles required = No. of tiles × Cost on 1 tile

➜ Cost of required tiles = 2,000 × 7.50

➜ Cost of required tiles = 2,000 × 7.50 = 15,000

➜ Cost of required tiles = Rs 15,000

➜ So, the cost of the tiles required is Rs 15,000.
