Answer 1

$\huge{ \bold{ \blue{answer}}}$

let the height of a triangular field be = H

then base = 3H

now cost of per hectare is 36 and total cost = 496

so area of field = 496 / 36 = 13 .5

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

therefore , 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 .

Answer 2

Answer:

Let the height of a triangular field be = H

Then base = 3H

Now cost of per hectare is 36 and total cost = 496

So area of field = 496 / 36 = 13.5

We know that area of triangle is 1 / 2 ×b ×h

Therefore , 1/2 ×3h ×h = 13.5

h^2 = 13 .5×2/3 =9

h = square root of 9 = 3

and base× 3h = 3×3 = 9 ans.

Answer is 9.
