Rs18,316

Rs17,136

Rs18,164

Rs17,085

Let’s break this down step by step:

- The triangle sides: 60 m, 112 m, and 164 m.

- Area (using Heron's formula):

- s = (60 + 112 + 164) / 2 = 168 m

- Area = v[168 × (168-60) × (168-112) × (168-164)]

- Area = v[168 × 108 × 56 × 4] = v(4064256) ˜ 2016 m²

- Cost to level = Area × Rate = 2016 m² × Rs 8.50 = Rs 17,136

Now, what this really means is:

- ? Option 2: Rs 17,136 is the correct answer.

- Option 1, 3, and 4 don’t fit the actual calculation, so you can skip them.
