l=2/3b
p=2(l+b)
75=2(2/3b+b)
75=2(5b/3)
75=10b/3
75*3=10b
225/10=b
b=22.5
p=2(l+b)
75=2(2/3b+b)
75=2(5b/3)
75=10b/3
75*3=10b
225/10=b
b=22.5

let the breadth of the rectangle be x
and the length of a rectangle be two third of x
it's given perimeter of the rectangle that 2*(l+b) = 75 m
2*(x+(2/3x))=75
(5/3)x=37.5
x=22.5
... hence breadth of the rectangle=22.5 m
and the length of the rectangle according with the question=15 m
