Question

the base of a triangular field is three times its height if the cost of cultivating the field at rupees 36 per hectare is rupees 46 find its base and height​

Answer 1

Let the height of the triangular field be h.
Then base of the triangular field = 3h.

Area of triangular field = 
 
Cost of cultivating 100 m2 = Rs 36.72
Cost of cultivating  metre2 = Rs 
According to question:

⇒ h2 = 90,000
⇒h = 300
Thus, height of the triangular field = 300 m.
And base of the triangular field = 3 × 300 = 900 m
