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 result:

S =  4743.5 m2

Solution:

S=160⋅ (160−119)⋅ (160−111)⋅ (160−90)=4743.5 m2
