## Task 1 - V00501

The fencing of a square garden is being renewed. It costs 992.00 DM. One meter of fencing is charged at 4.00 DM.

Calculate the area of this garden and convert the result into hectares.
The perimeter $u$ of a square with side length $a$ is $u=4a$. Since $\frac{992}{4}=248 \text{~m}$ of fencing was installed, $a=62 \text{~m}$.

For the area, $A=a^{2}=62^{2}=3844 \text{~m}^{2}$, i.e., approximately 0.38 ha.
