Correct question :

(a) 100 cm and 144 cm(b) 70 cm and 36 cm

Answer:

Given that:-

  • Length of tiles = 12cm
  • Breadth of tiles = 5cm.
  • Length and breadth of the rectangular region

To find:-

  • A number of tiles to be fitted in the rectangular region.

(a) Area of rectangle = 100 × 144

= 14400 cm

Area of one tile = 5 × 12

= 60 cm^2

Number of tiles = (Area of a rectangle) / (Area of one tile)

= 14400 / 60

= 240

          Hence, 240 tiles are needed

(b) Area of rectangle = 70 × 36

= 2520 cm^2

Area of one tile = 5 × 12

= 60 cm^2

Number of tiles = (Area of rectangle) / (Area of one tile)

= 2520 / 60

= 42

                    Hence, 42 tiles are needed.
