Question

floor of dimension 10.2 metre into 6 metre is to be tied with square tiles with its side is 60 cm how many times will be required to cover the floor.

Answer 1

Answer:

Step-by-step explanation:

dimension of rectangle:

length = 10.2m = 1020cm

width = 6m = 600m

area = 1020×600 cm^2

dimension of square tile = 60cm

area = 60×60 cm^2

Number of tiles = area of rectangle ÷ area of tile

number of tiles= 1020×600 / 60×60 = 170

Answer 2

Answer:

Sides of the floor =5m and 3m

Length=500cm and Breadth300cm [ 1m =100cm]

Area of the floor =lb=500×300=150000cm

2

.

Square tile : Side =25cm

∴ Area of a tile =25×25=625cm

2

∴ No. of tiles required = Area of the floor ÷ Area of a tile =150000÷625=240.

∴240 square tiles are required to cover the room.
