Sunflower Field

The trapezoidal sunflower field is located between two parallel paths spaced 230 meters apart. The lengths of the parallel sides of the field are 255 m and 274 m. How many tons of sunflower will come from this field if the hectare yield is 2.25 tons?

Correct answer:

m =  13.7 t

Step-by-step explanation:

$$\begin{gathered} h=230\text{m} \\ a=255\text{m} \\ c=274\text{m} \\ S=h\cdot (a+c)/2=230\cdot (255+274)/2=60835{\text{m}}^2 \\ {S}_2=S\to \text{ha}=S:10000\text{ha}=60835:10000\text{ha}=6.0835\text{ha} \\ m=S_2\cdot 2.25=6.0835\cdot 2.25=13.7\text{t} \end{gathered}$$
