Question

a square field has an area of 6.25 sq.km Find the cost of putting a fence around it at the rate of ₹10.5 per metre??​

Answer 1

Step-by-step explanation:

Find the length of the field:

Area = Length²

Given that area = 6.25m

Length² = 6.25

Length = √6.25

Length = 2.5 m

Find the perimeter:

Perimeter = 4 x Length

Perimeter = 4 x 2.5 = 10 m

Find the cost of fencing:

1 m = Rs 32.50

10 m = 32.50 x 10 = Rs 325

Answer: The cost is Rs 325
