The farmer

The farmer would like to first seed his small field. The required amount depends on the seed area. Field has a triangular shape. The farmer had fenced field, so he knows the lengths of the sides: 119, 111 and 90 meters. Find a suitable way to determine the area to be seeded?

Correct answer:

S =  4743.5 m²

Step-by-step explanation:

$S=\sqrt{160\cdot (160-119)\cdot (160-111)\cdot (160-90)}=4743.5{\text{m}}^2$
