Answer:
40000m and 80000m^2 respectively.
Step-by-step explanation:
If we let the altitude to be x cm and the base 2x. So the area of the triangle will be 1/2*base*altitude = 2x^2/2.
Cost of cultivation is Rs30 , the total cost of cultivating the field will be = Rs480, Area of the triangular field will be 480/30 = 16m^2.
Since, 1 hector = 10000m^2 so 16H will be 160000. Hence, x^2 = 160000 or x = 400m.
So altitude will be 400m and the base is 2*400=800m.
