Answer:

Side of square = 250 m

Perimeter of square = 4 x side

= 4 x 250 = 1000 m

Since, cost of fencing of per meter = Rs. 20

Therefore, cost of fencing of 1000 meters = 20 x 1000 = Rs. 20,000

Given -

  • Side of the square park is 250m.
  • Cost of fencing is Rs.20 per metre.

To find -

  • Total cost of fencing the park.

Solution -

As given in the question that each side of the square park is 250m.

The figure below shows the given square park.

\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\multiput(0,0)(4,0){2}{\line(0,1){4}}\multiput(0,0)(0,4){2}{\line(1,0){4}}\put(-0.5,-0.5){\bf D}\put(-0.5,4.2){\bf A}\put(4.2,-0.5){\bf C}\put(4.2,4.2){\bf B}\put(1.5,-0.6){\bf\large 250\ m}\put(4.4,2){\bf\large 250\ m}\end{picture}

Fencing the park means that we need to find the perimeter of the park. Since this is a square, therefore it's perimeter will be ..

\large\underline{\boxed{\red{Perimeter_{(Square)} = 4 \times side}}}

\tt\dashrightarrow{Perimeter = 4 \times 250}

\tt\dashrightarrow{Perimeter = 1000\: m}

This means that we need 1000 metres of fence for fencing the whole park. It is given that rate of fencing is Rs.20 per metre.

\bf\dashrightarrow{Total\: cost = Perimeter \times Rate\: of\: fencing}

\tt\dashrightarrow{Total\: cost = 1000 \times 20}

\tt\dashrightarrow{Total\: cost = Rs.20,000}

Hence,

  • Total cost of fencing the park is Rs.20,000.
