Question

The base of a triangular field is three times its height. If the cost of cultivating the field
t36 per hectare is 486, find its base and height (1 hectare = 10000 m2​

Answer 1

Answer:

Step-by-step explanation:

Let the height of triangular field be =h, then base = 3h

Now cost of per hectare is 36 and total cost =486

so, area of field = 486/36=13.5

we know that area of triangle is 1/2*b*h

therfore, 1/2*3h*h=13.5

h^2=13.5*2/3=9

h= under root 9=3

and base =3h=3*3=9 ans
