The formula to calculate the Area of Circular Sector given Arc Length is:
\[ A = \frac{r \cdot l_{\text{Arc}}}{2} \]
The Area of a Circular Sector is the total quantity of plane enclosed by the Circular Sector. The Radius of a Circular Sector is the radius of the circle from which the Circular Sector is formed. The Arc Length of a Circular Sector is the length of the curved boundary edge of the Circular Sector.
Let's assume the following values:
Using the formula:
\[ A = \frac{5 \cdot 4}{2} = 10 \]
The Area of the Circular Sector is 10 square meters.
