Question

determine the longest rod which will be required to measure exactly the length 60m 90cm and breadth 37m 80cm of a plot of land​

Answer 1

Answer:

to determine the longest rod to measure exactly the length of plot you need to find the HCF of these no.

60 factors=2,2,3,5

90 factors=2,3,3,5

37 factors=37

80 factors=2,2,2,2,5

HCF=2×3×5×37

=990
