A room which is 40m long and 15m broad is to be paved with tiles,each measuring 6cm by 5cm. Find the number of tiles required. Please solve step by step..
Answers
length of room = 40m
breath of room = 15m
area of room = l × b
= 40×15 = 600m square
length of tile = 6cm
breadth of tile =5cm
area of tile =30Cm
(1 m = 100 cm ) so 600m = 60000cm
tiles required = 60000/30
=2000

Answer:
2000 tiles required.
Step-by-step explanation:
Length of room = 40 m
Breadth of room = 15 m
Area = l × b
= 40 × 15 m
40 m = 40000 cm.
15 m = 15000 cm
= 40000 × 15000
60000000 cm²
Area of room is 60000000 m².
length of tile = 6 cm
breadth of tile = 5 cm
Area = l × b
= 6 × 5 cm
= 30 cm²
Area of tile is 30 cm².
No. of tiles needed for covering the room is ==
( 60000000 m²÷ 30 cm² )
= 2000
2000
hence the numbers of tiles needed are 2000.
