Answer 1

fencing =circumference
circumference=2×22/7×28/2
=88cm
cost=rs300 per metre
total cost=300×88
=rs26400

Answer 2

The total cost of wooden fencing around a circular garden is Rs.26400

Step-by-step explanation:

Diameter of circular garden = 28 m

Radius of circular garden = $\frac{28}{2} = 14 m$

Circumference of circle = $2 \pi r = 2 \times \frac{22}{7} \times 14 =88 m$

Cost of fencing 1 m = Rs.300

Cost of fencing 88  m = $300 \times 88 = 26400$

Hence the total cost of wooden fencing around a circular garden is Rs.26400
