Question

the base of the triangular field is two times its altitude. if the cost of cultivating the field at ₹250 per hectar is ₹1000, find the area of the field.​

Answer 1

Answer:

Area of the field = 200m

Step-by-step explanation:

Area of the field is given by -

Area of the field = total cost / rate of cultivation

Area of the field = 1000/250

Area of the field = 4 hectares

Area of the field = 40000 m^2

But area of the field is given by -

Area of the field = 1/2 × base × altitude

Area of the field = 1/2 × 2×altitude × altitude

40000 = altitude^2

Altitude = √(40000)

Altitude = 200 m
