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
