Question

What is the cost of fencing a square park of side 50 m at rate of Rs. 21 per meter?

Answer 1

Question :-

• Find the Cost of Fencing a Square Park of Side 50 m at the rate of Rs. 21 per Metre .

⠀⠀⠀⠀⠀⠀

Answer :-

• Cost of Fencing is Rs. 2100

⠀⠀⠀⠀⠀⠀

Explanation :-

• Here, Side of Square Park is given 50 meter . Rate of cost for Fencing is Rs. 21 . And, we have to calculate the Cost of Fencing .

⠀⠀⠀⠀⠀⠀

➻ First, we will find the Perimeter :-

$\dag \: \: \sf{ Perimeter \: = \: 4 \: \times \: side}$

$\Longrightarrow \: \: \sf{Perimeter \: = \: 4 \: \times \: 50}$

$\Longrightarrow \: \: \sf{Perimeter \: = \: 200 \: m}$

⠀⠀⠀⠀⠀⠀

➻ Now, let's find Cost of Fencing :-

$\dag \: \: \sf{ Cost \: of \: Fencing \: = \: Perimeter \: \times \: Rate}$

$\Longrightarrow \: \: \sf{ Cost \: of \: Fencing \: = \: 200 \: \times \: 21}$

$\Longrightarrow \: \: \sf{Cost \: of \: Fencing \: = \: Rs. \: 2100}$

⠀⠀⠀⠀⠀⠀

Hence :-

• Cost of Fencing = Rs. 2100

Answer 2

Answer:

____________________________________

➮ Given-:

• Side of a square park = 50 m
• Cost of fencing = Rs. 21 per meter

____________________________________

➮ To Find-:

• Total cost of fencing a square park = ?

____________________________________

➮ Using Formula-:

• Perimeter of a Square = 4 × Side

____________________________________

➮ Calculation-:

$\bigstar \: \boxed{ \sf{Perimeter \: of \: a \: Square \: = \: 4 × Side}} \\ \\ \sf \: \implies \: 4 \times 50 \\ \\ \boxed{ \sf \: \implies \: 200 \: m}$

• Perimeter of a Square = 200m

____________________________________

$\scriptsize \boxed{ \sf{Total \: cost \: of \: fencing \: of \: a \: square \: park \: = Perimeter × Rate}} \\ \\ \sf \: \scriptsize \: \implies \: 200 \times 20 \: \\ \\ \boxed{ \sf \: \scriptsize \: \implies \: 2100}$
