Question

A field, in the form of a rhombus, has its diagonals as 40 m and 25 m long respectively. Find the cost of watering the field at 12 paise per m².

Answer 1

Given: A rhombus with diagonals d₁ = 40 m and d₂ = 25 m; rate = 12 paise per m².

Step-wise calculation:

1. Area of a rhombus = `1/2 xx d_1 xx d_2`.

2. Area = `1/2 xx 40 xx 25`

= 500 m²

3. Cost (in paise) = Area × Rate

= 500 × 12

= 6000 paise

4. Convert to rupees: 6000 paise

= 6000 ÷ 100

= ₹ 60

The cost of watering the field is 6000 paise, i.e. ₹ 60.
