Question

17. A triangular park has sides 60 m, 40 m and
26 m. Gardener has to put a fence all around
its boundary and also plant grass inside. Find
the area in which grass will be planted. Also,
calculate the cost of fencing it with barbed wire
at the rate of 30 per metre, leaving a space
for a 2 m wide gate on one side,​

Answer 1

Answer:

Cost: 3720 Rs.

Step-by-step explanation:

Area of triangle = base * height

                                      2

however this question has not given a figure nor has specified the height and base... if possible, please update the question with the figure.

so lets move on with the perimeter:

60 + 40 + 26 = 126 m

Cost = 30 Rs. per metre

Total cost of fencing whole garden = 30 * 126 = 3780 Rs.

           

We must leave out 2 metres so 30*2 = 60 Rs.

Final cost = 3780 - 60 = 3720 Rs.

Thus the cost required for fencing it is 3720 Rs.
