Answer 2

Question

• Side of the square park is 350m at rate ₹30 per metre.

To find

• The perimeter of square and rate of it.

Solution

• In the given question it has written fencing it means the Perimeter.

• So whenever it will come like fencing so it means we have to find the perimeter.

${\fcolorbox{blue}{black}{\purple{\:\:\:\:\:\:\: Perimeter of Square = 4 × Side\:\:\:\:\:\:}}}$

By, using the formula let's solve the given question

• $\sf\pink{Side \ given}$ ⟹ $\sf\red{350}$
• $\sf\blue{Perimeter \ is}$ ⟹ $\sf\green{350m × 4 }$

$\begin{gathered}\qquad\quad\boxed{\bf\gray{\mid{\overline{\underline{\bigstar\: Perimeter = 1,400 \: :}}}}\mid}\\\\\end{gathered}$

Now, we have to find the cost rate of perimeter 1,400

Given the cost of per metre ⟹  ₹30

$\sf\green{Perimeter \times Cost} \sf\orange\rightarrow \sf\pink{Cost \ of \ 1,400m }$

$\sf\blue{1,400 \times ₹30} \sf\orange\rightarrow \sf\red{₹42,000}$

$\sf{Hence, verified!}$

•°• The cost of fencing square park of side 350m at a rate of ₹30 is $\sf{1,400}$.
