SUMMARY
To calculate the area of a rectangular plate with dimensions of 23.2 ± 0.2 cm (length) and 9.0 ± 0.1 cm (width), the area is determined using the formula A = length × width. The calculated area is 208.88 cm². The uncertainty in the area can be derived using the formula for propagation of uncertainty, which results in an uncertainty of approximately ± 0.46 cm². Referencing the provided resource from Buffalo State Physics Education can further clarify the methods used for these calculations.
