Question

A man covers a distance of 48m while going around a square field twice. Find the side of the field and the length of the wire needed to fence around it thrice. Also, find the cost of wire ,if the cost of 1metre wire is ₹2.75.​

Answer 1

2 rounds = 48 m

1 round = 24 m = Perimeter of the square field

Perimeter = 4(side)

4(side) = 24 => side = 6 m

3 rounds = 24×3 = 72 m

Rate = ₹2.75/m

Cost = 72×2.75 = ₹198

Answer 2

Answer:

72 meters of wire and cost is  rs 198

Step-by-step explanation:

Perimeter= 4xside

Perimeter x 2= 48

Perimeter= 48/2

Perimeter= 24

24= 4xSide

Side= 24/4

Side=6

Perimeter= 4S

6x4=24

As fencing is thrice= 24x3= 72

Cost=72x2.75

Rs:198
