The formula for area depends on the shape you are referring to. Here are some common formulas for area:
1. Area of a Rectangle
Area=length×width\text{Area}=\text{length}\times \text{width}Area=length×width
2. Area of a Square
Area=side2\text{Area}=\text{side}^2Area=side2
3. Area of a Triangle
Area=12×base×height\text{Area}=\frac{1}{2}\times \text{base}\times \text{height}Area=21×base×height
4. Area of a Circle
Area=π×radius2\text{Area}=\pi \times \text{radius}^2Area=π×radius2
5. Area of a Parallelogram
Area=base×height\text{Area}=\text{base}\times \text{height}Area=base×height
