Question

the base of a triangle field four times of altitude if the cost of cultivating the fans at the rupees 18 per square metre is rupees 214 find the base and height ​

Answer 1

Answer:

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

this is not the answer to your question but you will get the clue for your answer!!
