Question

13. The cost of fencing a square park at the rate of 20 per metre is rupees 8000. Find the length of side of the square.​
step by step

Answer 1

Answer:

• 100metres is the required length of the park.

Step-by-step explanation:

According to the Question

It is given that ,

• Total cost of fencing = 8000
• Rate of fencing = 20 per metre

we have to calculate the length of the side of the square .

As per given question the square park is fencing so it means that we need to calculate the perimeter of the square park .

•Perimeter of Park = Total Cost of fencing/Rate of fencing

substitute the value we get

➻ Perimeter of Park = 8000/20

➻ Perimeter of Park = 400m

Now, calculating the length of side of Square park.

Let the side of Square be x m

• Perimeter of Square = 4 × Side

➻ 400 = 4×x

➻ x = 400/4

➻ x = 100m

• Hence, the length of the side of Square park is 100 metres.

Answer 2

Given :-

The cost of fencing a square park at the rate of 20 per metre is rupees 8000.

To Find :-

Length of side

Solution :-

Cost = Perimeter × Rate

8000 = Perimeter × 20

8000/20 = Perimeter

800/2 = Perimeter

400 = Perimeter

Now

Side = Perimeter/4

Side = 400/4

Side = 100 m
