Land

Rectangular triangular land has area 30 square meters and 12 meters long leg. How many meters of the fence do you need for fencing this land?

Correct answer:

x =  30 m

Step-by-step explanation:

$$\begin{gathered} A=30{\text{m}}^2 \\ a=12\text{ m } \\ A={\displaystyle \frac{ab}{2}} \\ b=2\cdot A\mathrm{/}a=2\cdot 30\mathrm{/}12=5\text{ m } \\ c=\sqrt{a^2+b^2}=\sqrt{12^2+5^2}=13\text{ m } \\ x=a+b+c=12+5+13=30\text{ m} \end{gathered}$$
