The field has a rectangular shape with a width of 180 m and a circumference of 940 m. How many hectares acreage has field?

Correct answer:

x =  5.22 ha

Step-by-step explanation:

$$\begin{gathered} a=180 \\ o=940 \\ b=o\mathrm{/}2-a=940\mathrm{/}2-180=290 \\ S=a\cdot b=180\cdot 290=52200 \\ x=S\mathrm{/}100^2=52200\mathrm{/}100^2={\displaystyle \frac{261}{50}}={\displaystyle \frac{261}{50}}\text{ ha}=5.22\text{ ha} \end{gathered}$$
