The base of a triangular field is three times its altitude. If the cost of cultivating the field at Rs. 24.68 per hectare be Rs. 333.18, find its base and height.

Area of the field = Total cost/rate = (333.18/25.6) = 13.5 hectares
$13.5*10000m2=135000m2$ 
Let altitude = x metres  and  base = 3x metres.
Then,  $\frac{1}{2}*3x*x=135000\Rightarrow x2=90000\Rightarrow x=300$ 

Base = 900 m and Altitude = 300 m.
