Question

The sides of a triangular field are 1200cm, 1600cm and 2000cm.It is rent out at $5000 per hectare. Find the rent?​

Answer 1

Answer:

herons formula

$s = \frac{a+b+c}{2}$

A=$\sqrt{s(s-a)(s-b)(s-c)}$

SO,

1200+1600+2000=4800

4800/2=2400

$\sqrt{2400(2400-1200)(2400-1600)(2400-2000)}$

$\sqrt{2400 X1200X800X400}$

=960000cm sq.

=0.0096 hectare

=0.0096 x $5000

= $48
