The farmer

The farmer would like to first seed his small field. The required amount depends on the seed area. The field has a triangular shape. The farmer had a fenced field, so he knew the lengths of the sides: 73, 117, and 63 meters. Find a suitable way to determine the area to be seeded.

Final Answer:

S =  2020.56 m²

Step-by-step explanation:

$$\begin{gathered} a=73\text{m} \\ b=117\text{m} \\ c=63\text{m} \\ s=\frac{a+b+c}{2}=\frac{73+117+63}{2}=\frac{253}{2}=126.5\text{m} \\ S=\sqrt{s\cdot (s-a)\cdot (s-b)\cdot (s-c)}=\sqrt{126.5\cdot (126.5-73)\cdot (126.5-117)\cdot (126.5-63)}=2020.56{\text{m}}^2 \end{gathered}$$
