4in \( A= \) in

It seems like you're asking for the area \( A \) of a shape, but the shape is not specified. If you are referring to a square with a side length of 4 inches, the area can be calculated using the formula for the area of a square: \[ A = \text{side}^2 \] For a square with a side length of 4 inches: \[ A = 4 \, \text{in} \times 4 \, \text{in} = 16 \, \text{in}^2 \] If you meant a different shape (like a rectangle, circle, etc.), please provide more details so I can assist you further!
