Area lb=750
perimeter 2(l+b)=110
we know that
(l+b)^2=(l-b)^2+4lb
55^2=(l-b)^2+4*750
3025=(l-b)^2+3000
(l-b)^2=3025-3000
(l-b)^2=25
(l-b)=5
so,
solve equations
l+b=55 and l-b=5
l=30
substitute in any of the above equations u will get 
b=25
therefore the dimensions of the farm are 30m and 25m

Let length and breadth of the farm be l, b then 2(l+b)=110 i.e. l+b=55. And the area is lb=750 Then l-b=√{(l+b)^2-4lb}=√{(55^2)-4(750)}=√25=5. Hence, 2l=60 i.e. l=30 and b=25
