Answer Posted / geo
length=x does not imply breadth=36-x
given that thread cover length is twice and breadth once
once a book covered by length means twice the length is covered
so if twice length is covered then 4*length is covered
likewise consider breadth
4x+2y=36.
so u can give some random values to x and y
some possible set for x and y are
(8,2),(7,4),(6,6)
(6,6) -> 36sqcm
