Answer:

(a) Area of rectangle = 100 × 144

= 14400 cm

Area of one tile = 5 × 12

= 60sq.cm

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

= 14400 / 60

= 240sq.cm

Hence, 240 tiles are needed

(b) Area of rectangle = 70 × 36

= 2520sq.cm

Area of one tile = 5 × 12

= 60sq.cm

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

= 2520 / 60

= 42

Hence, 42 tiles are needed.
