surrounding the plot with a fence at 5.70 per metre.​

Answer 1

Answer:

₹421.80

Step-by-step explanation:

Area of rectangle = l×b

Given, area = 340 m², breadth = 17 m

=> Length = Area/Breadth = 340/17 m = 20 m

Perimeter = 2(l+b) = 2(20+17) m = 2(37) m = 74 m

Cost of fencing per m = ₹5.70

Total cost of fencing = ₹5.70 × 74 = ₹421.80
