Question

Find the number of tiles required to cover a room 300m long and 250 m broad. If the length of

each title is 5m and breadth is 3m.​

Answer 1

5000 tiles

Step-by-step explanation:

area of room is = 300 *250

= 75000

area of one tile = 5*3

= 15

then no. of tiles need to cover the room

= 75000/15= 5000

Answer 2

Answer

✦ Given:-

• Length of tiles = 5m

• Breadth of tiles = 3m

• Length of room = 300m

• Breadth of room = 250m

✦ To Find:-

• Number of tiles required to cover the room

✦ Concept/Formula Used:-

▪Area of room = length × breadth

▪Number of tiles used =

Area of room ÷ Area of tiles

✦ Solution:-

★ Finding area of room:

Area of room

= area of rectangle

= length × breadth

= 300m × 250m

= 75000m²

Area of room = 75000m

★ Finding area of tiles:

Area of tiles

= Area of rectangle

= length × breadth

= 5m × 3m

= 15m²

Area of tiles = 15m²

★ Finding number of tiles used to cover the room:

By using concept;

Number of tiles used

= Area of room ÷ Area of tiles

Putting the values in concept;

Number of tiles used

= 75000 ÷ 15

= 5000

∴ 5000 tiles used to cover the whole room.
