Question

6. The base of a triangular field is three times its height. If the cost of cultivating the field
at 36 per hectare is 486, find its base and height (1 hectare = 10000 m²).​

Answer 1

Step-by-step explanation:

Let the height of triangular field be h,

then base = 3h

Now the cost of per hectare is 36 and total cost- 486

So, area of field- 486/36- 13.5

We know that area of triangle- 1/2*base*height

therefore-1/2*3h*h- 13.5

h = under root 9= 3

and base= 3h = 3*3 = 9 Ans
