A community hall is 16m 50cm long and 15m
25cm wide.It is to be paved by square marble stone tiles.Find the
largest size of each tile and least number of tiles required.
length = 16m50cm
= 1650 cm
Width = 15m25cm
Side of the Square marble Stone = H.C.F of 1650 and 1525
So first calculate HCF of 1650 and 1525
Hcf of 1650 and 1525 = 25
Therefore NUmber of tiles required = total area of hall / area of square marbles
= 1650*1525 / 25*25
Hope this helps you!!!
