Question

find the cost of fencing a square Park of side 140 m at the rate of rupees 120 per metre .​

Answer 1

Answer:

168/-

Step-by-step explanation:

Side if Square Park = 140m

perimeter of Square= side × 4

= 140 × 4

= 560m

Cost of Fencing per

meter = 120/-

cost of fencing for square park = 560 × 120

= 67,200 /-

Answer 2

Given :-

• Side of Square Park = 140m
• Rate of Fencing = Rs 120 per m

To Find :-

• Total Cost of Fencing

Solution :-

❏ As we know that, Fencing is done on the boundary so , we will be finding the Perimeter of the square park . Then we will Multiple the rate of Fencing with total perimeter.

⟾ Perimeter of Square Park = 4 × Side

⟾ Perimeter of Square Park = 4 × 140

⟾ Perimeter of Square Park = 560m

Now,

➟ Cost of 1m of fencing = Rs 120

➟ Cost of 560m of fencing = 120 × 560

➟ Cost of 560m of fencing = Rs 67,200

Thus, Total Cost of Fencing is Rs 67200
