A garden is in the equilateral triangle shape. Its base is $22 c m$ and breadth is $18 c m$ . Find the cost of levelling the garden at $R s 5$ per $m^{2}$ .

Open in App

Solution

Area of garden $= \frac{1}{2} \times$ base $\times$ height
$= \frac{1}{2} \times 22 \times 18 = 198 c m^{2} = 198 \times 10^{- 4} m^{2}$
$\Rightarrow$ Cost $=$ Rs. $\frac{5 \times 198}{10^{4}} = \frac{990}{10^{4}} = 0.099$ Rs.
