Answer 1

Answer:

₹1250

Step-by-step explanation:

Find the length and breadth of the room in cm:

Length of the floor = 14 m = 1400 cm

Breadth of the room = 12 1/2 m = 1250 cm

Given that the tiles are 10 cm by 7 cm

Find the number of tiles to be laid length-wise:

Number of tiles  = 1400 ÷ 7 = 200 tiles needed

Find the number of tiles to be laid breadth-wise:

Number of tiles  = 1250 ÷ 10 = 125 tiles needed

Find the total number of tiles need:

Total number of tiles = 200 x 125 = 25000

Find the cost of the tiles:

100 tiles = ₹5

25000 tiles = 5 x 250 = ₹1250
