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
