Question
What is the minimum number of square marbles required to
tile a floor of length 4 metres 35cm and width 3 metres 60 cm? ÂSolution
If there is a requirement of minimum number of tiles , we must take the maximum size of the side. The side of square tile required to tile a floor of length 435cm & 360cm = HCF (435,360) = 15cm . So area of 1 square tile = 15cm ×15cm & Area of the floor = 435cm×360cm.                                 So number of tiles = Area of floor/ area of 1 tile = (435cm×360cm)/(15cm ×15cm) = 29 × 24 = 696.
