42Q:
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.

A) B=900;H=300
B) B=300;H=900
C) B=600;H=700
D) B=500;H=900

Answer: A) B=900;H=300

Explanation:
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, 12*3x*x=135000⇒x2=90000⇒x=300

Base = 900 m and Altitude = 300 m.
