Solution
Given:
Side of the rhombus shaped garden = 30 m
Altitude = 16 m
Now, area of a rhombus = side x Altitude
\[ \therefore\text{ Area of the given garden }=30\times16=480 m^2 \]
\[ {\text{ Also, it is given that the rate of levelling the garden is } \text{ Rs 2 per }1m}^2 .\]
\[ \therefore {\text{ Total cost of levelling the complete garden of area }480 m}^2 =480\times2= \text{ Rs }960\]
