The area of a field in the shape of a regular hexagon is 2400\(\sqrt {3}\) m². The cost of fencing the field at ₨.19.20/ metre is: |
₨. 4,608 ₨. 4,688 ₨. 6,608 ₨. 4,758 |
₨. 4,608 |
Area of a hexagon = 6 x area of one equilateral tringle = 6 x \(\frac{\sqrt {3}}{4}\) side² = 2400\(\sqrt {3}\) side² = 1600 s = 40 Perimeter = 6 x side = 6 x 40 = 240 m Cost = 240 x 19.20 = ₨. 4,608 |
