Answer 1

Hii There!!!


Since, given triangle is an equilateral triangle.
So, length of each side will be = 12m

Now, Area of an equilateral triangle = √3/4 a^2

where, a is the side of an equilateral triangle.


=> √3/4 × 12 × 12

=> √3 × 3 × 12

=> 36√3 m^2

Hence, area of equilateral triangle = 36√3 m


Cost of leveling per m^2 = 5 ₹

So, cost for 36√3 m^2
= 36√3 × 5

=> 180√3

Or, 180 × 1.73

=> 311.4 ₹ is the answer.




Hope it helps
