Question

find the cost of fencing a square park of side 125m at the rate of ₹20 per meter​

Answer 1

Step-by-step explanation:

Side of square park = 125 m

Perimeter of park = 4a

= 4 x 125 m

= 500 m

Cost of 1 m fencing wire = Rs 20

Cost of 500 m fencing wire = 20 x 500

= Rs 10,000

:. It would cost Rs 10,000 to fencing the park

$\dashrightarrow$ Here the question has given us the side of a square park that is 125 m and rate of fencing per metre that is ₹20. Now, the question has asked to find the cost of fencing that square park. So, first of all we will find the perimeter of the square and then we will multiply the per metre rate of fencing with the perimeter and we will get the cost of fencing.

ANSWER:-

✪ Perimeter of the square = 500 m

✪ Cost of fencing that square park = ₹ 10,000

GIVEN:-

» Side of the square = 125 m

» Fencing rate per metre = ₹ 20

TO FIND:-

➬ Cost of fencing = ?

FORMULA:-

☞ Perimeter of square = 4 × S

☞ Cost of fencing = P × R

Where,

• S = Side
• P = Perimeter
• R = Rate

SOLVING BY APPLYING THE FORMULA:-

• Finding the perimeter:-

➢ Perimeter = 4 × 125

➢ Perimeter = 4 × 125 = 500

➢ Perimeter = 500 m

Thus, the perimeter is 500 m.

• Finding the cost of fencing:-

➢ Cost = 500 × 20

➢ Cost = 500 × 20 = 10,000

➢ Cost = ₹ 10,000

Thus, the cost of fencing that square park is ₹ 10,000.
