Answers
Answer:
2000 tiles
₹10000
Step-by-step explanation:
Length and Breadth of room = 500cm , 400cm
Area of room = L×B
= 500 × 400
= 2,00,000cm²
Area of square tiles = 10×10
= 100cm²
No. of tiles required = 20000/100
= 200 tiles per cm
Cost of tiles = 2000×5
= ₹10000

Answer:
Length of rectangular floor of room= 5m
breadth of rectangular floor= 4m
∴Area of rectangular floor = length*
breadth
= 5*4
= 20 m²
Side of Square tile= 10cm
Now we need to convert Side of Square tile in meters= 10/100=0.1m
Area of square tile = side²
= 0.1²
=0.01 m²
Now
number of tiles required to cover the floor =(ar of floor of room)/(ar of 1 tile)
= 20/0.01
=2000
number of tiles required =2000tiles
Now cost of 1tile=Rs 5
total cost = 5*2000
