Question

A floor 3 m long and 2m wide is to be covered with square tiles of lenghth 10 cm .Find the cost of flooring it, if the cost of tiles is Rs.150 per 100 tiles.

Answer 1

hello friend

good morning

given :-

length of the floor = 3m

breadth of the floor = 2m

area of the floor = l × b

= 3 × 2

= 6m²

length of the side of the square tile is given 10cm = 0.1m

area of the square tile = side × side

= 0.1 × 0.1

= 0.01m²

hence, no. of square tiles required for flooring the floor = 6/0.01

= 600 tiles are required.

ATQ, cost of 100 tiles is = ₹150

therefore cost of 1 tile = 150/100

= ₹1.5

hence, total cost of flooring = 600 × 1.5

= ₹900

I hope it will help you..

Answer 2

Heya !!!

Length of floor = 3 m

Breadth of floor = 2 m

Area of floor = Length × Breadth = 3 × 2 m = 6 m²

Side of square tiles = 10 cm = 0.1 m

Area of square tiles = 0.1 × 0.1 = 0.01 m²

Number of tiles required to covered the floor = Area of floor / Area of each square tiles

=> 6/0.01

=> 600

Cost of 100 square tiles = 150

Cost of each square tiles = 150/100

=> Rs 1.5

Therefore,

Cost of 6 tiles = 6 × 1.5

=> Rs 900

THANKS. :-)
