Question

A rectangular courtyard 3.78m long and 5.25m broad is to be proved exactly with square tiles, all of the same size. What is the minimum number of such tiles?

Answer 1

Explanation:

length = 3.78 m = 378 cm

broad = 5.25 m = 525 cm

size of largest tile = hcf of 378 and 525 = 21

no of tiles = area of floor / area of one tile

=>no. of tiles = (378 × 525) / (21×21)

so, total no. of tiles are 450.
