A garden is in the form of a rhombus whose side is 30 metres and the corresponding altitude is 16 m.
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.
Solution:
Given:
Side of the rhombus shaped garden $=30 \mathrm{~m}$
Altitude $=16 \mathrm{~m}$
Now, area of a rhombus $=$ side $\times$ altitude
$\therefore$ Area of the given garden $=30 \times 16=480 \mathrm{~m}^{2}$
Also, it is given that the rate of levelling the garden is Rs 2 per $1 \mathrm{~m}^{2}$.
$\therefore$ Total cost of levelling the complete garden of area $480 \mathrm{~m}^{2}=480 \times 2=\mathrm{Rs} 960$
