It depends on the shape.
Square: Area = side2 or length x width
Rectangle: Area = length x width
For a circle: Area = pi x r2
Be sure to use proper units. Whether use use inches, feet, centimeters, meters, or some other length unit, the surface area will always be that unit squared (in2, ft2, cm2, m2 ...).

What is the formula of cross sectional area for a coin?
The formula for the cross-sectional area of a coin is calculated using the formula for the area of a circle, which is A = πr^2. In this formula, A represents the area, π is a constant approximately equal to 3.14159, and r is the radius of the coin. By substituting the radius of the coin into the formula, you can calculate the cross-sectional area of the coin.
