Area of triangular field = 1/2 × base × height
= 1/2 × 3x × x m^2
= 3x^2/ 2 × 10000 hect.
According to question,
3x^2 / 2× 1000 × 96 = 3600
x^2 = 3600×2×10000 / 3 × 96 = 250000
x = 500m

Therefore, Height of triangular field = 500m
and, Base of triangular field = 3 × 500 = 1500m

Answer:

let the length of the base=3x

the length of the height=x

rate=36/10000

cost=486

area of field =486x10000/36

1/2x based x height=135000

3x*x=135000x2

3x^2=270000

x^2=270000/3

x^2=90000

x=√90000

x=300m

height =300m

base=3x300

=900m
