A rectangular courtyard is 57m 50 cm long and 22m broad. Determine the least possible number of square stones of the same size required to pave it

Answer 1

the dimensions of the small stones must divide those of the courtyard.

GCD(5750,2200) = 50
so, the largest stones can be 50x50 cm. Thus the area, in terms of stones is
(5750/50) * (2200/50) = 115*44 = 5060
