Question

10
How many tiles with dimensions 6 cm x 10 cm will be needed to fit in a region whose length and breadth are respectively?
(ii) 90 cm ×40 cm​

Answer 1

Step-by-step explanation:

Area of region = 90 * 40

= 3600

Area of tile = 6 * 10

= 60

Number of tiles = 3600/60

= 60

Answer 2

Answer:

60 tiles are required to fill the region

Step-by-step explanation:

Area of the Region = length x breadth

here  l= 90 cm , b = 40 cm

Area of the region is = lb = 90 x 40  = 3600 square cm

Area of the tiles = 6 cm x 10 cm = 60 square cm

Number of tiles required to fill the region is

= Area of the region / Area of the tile

= 3600 / 60

= 60 tiles

60 tiles are required to fill the region
