What does formaula for area?

The formula for the area depends on the shape in question. For a rectangle, the area is calculated as ( \text{Area} = \text{length} \times \text{width} ). For a triangle, the area is given by ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ). For a circle, the area is calculated using the formula ( \text{Area} = \pi r^2 ), where ( r ) is the radius.
