$\huge \color{violet}Answer$

Let the length of the field be 9x and breadth be 5x.

Let the length of the field be 9x and breadth be 5x.9x×5x=14580

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2 =324

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2 =324x=18

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2 =324x=18Hence, length=162m and breadth=90m.

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2 =324x=18Hence, length=162m and breadth=90m.Perimeter = 2(l+b)=2(162+90)=2(252)=504m

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2 =324x=18Hence, length=162m and breadth=90m.Perimeter = 2(l+b)=2(162+90)=2(252)=504mTherefore,

Let the length of the field be 9x and breadth be 5x.9x×5x=1458045x 2 =14580x 2 =324x=18Hence, length=162m and breadth=90m.Perimeter = 2(l+b)=2(162+90)=2(252)=504mTherefore,Cost of fencing = 504×3.25=1638 Rs.
