Question

find the cost of fencing a square park of side 250m at the rate of rupees 20 per metre

Answer 1

hii!!

here's Ur answer..

given the side of the square park = 250m

perimeter of the square park = side × 4

= 250 × 4

= 1000m

hence, cost of fencing the park at the rate of ₹20 per m = 1000 × 20 = ₹20000

hope this helps.....

Answer 2

each side of the park = 250 m
thus,
its perimeter = 250×4=1000m

since the rate of cost of fencing = ₹20/m

therefore,
cost=1000×20
cost=₹20000
