(A): Let the other number be y.
HCF × LCM = Product of numbers
11 × 7700 = 275 × y
y = 308
(A): Let the other number be y.
HCF × LCM = Product of numbers
11 × 7700 = 275 × y
y = 308
(C): Two plots have same perimeter:
So, 60 × 3 = 2 × ( length + 30)
90 = length + 30
Length = 60 m
Hence, area = 60 × 30 = 1800 sq. m
