Question

A path is to be made around a park whose shape is that of an equilateral Triangle. each side of the park is 35 m.find the cost of making the path,if it cost 70 per metre.​

Answer 1

Answer:

7350 is the cost please mark me as brain list and follow me

Answer 2

Therefore the cost of making the path is Rs.7350.

Step-by-step explanation:

Equilateral triangle:

• The all sides of an equilateral triangle are congruent .
• Each angle of an equilateral triangle are congruent.
• The sum of all angles is 180°.

• The perimeter of an equilateral triangle = 3×side.

• The area of equilateral triangle is $=\frac{\sqrt{3} }{4} side^2$  

Given that, each side of the park is 35 m.

Therefore the perimeter of the equilateral triangle is = (3×35)cm

                                                                                        =105 cm

[The unit of cost is not given in the question,So consider the unit of cost as Rs.}

The cost of making path is Rs 70 per meter.

Therefore the cost of making the path = (perimeter× cost per meter)

                                                                =Rs.(105×70)

                                                                =Rs. 7350
