Answer:
Area of rectangle = length*width
(a)Area of rectangle = 100*144
= 14400 cm
Area of one tile = 5*12
= 60 cm2
Number of tiles = (Area of rectangle) / (Area of one tile)
= 14400 / 60
= 240
Hence, 240 tiles are required
(b) Area of rectangle = 70*36
= 2520 cm2
Area of one tile = 5*12
= 60 cm2
Number of tiles = (Area of rectangle) / (Area of one tile)
= 2520 / 60
= 42
