Question

A garden is in the form of a rhombus whose side is 30 metres and the corresponding altitude is 16 m. Find the cost of levelling the garden at the rate of Rs 2 per m².

Answer 1

$$\begin{gathered} \text{Given:} \\ \text{Side of the rhombus shaped garden = 30 m} \\ \text{Altitude = 16 m} \\ \text{Now, area of a rhombus = side×altitude} \\ {\text{∴ Area of the given garden=30×16=480 m}}^2 \\ {\text{Also, it is given that the rate of levelling the garden is Rs 2 per 1m}}^2\text{.} \\ \therefore \mathrm{T}{\text{otal cost of levelling the complete garden of area 480 m}}^2\text{=480×2= Rs 960} \end{gathered}$$
