A rectangular courtyard is 57m and50cm long and 22m broad determine the least possible number of square stones of the same size required to pave it
Answered by Steve
In terms of cm,

57m 50cm = 5750cm
22m = 2200cm

The greatest common factor can be found using

5750 = 2 * 5^3 * 23
2200 = 2^3 * 5^2 * 11

So, the GCF is 2*5^2 = 50

Using 50cm stones, the courtyard is 115x44 = 5060 stones
