Firstly, the base is a rectangle (specifically, an oblong). There is a general formula for its area (B):


B=\text{ (width)}\cdot(length)

The trick behind the question is the units of the width (cm) and the length (mm). Due to the options, we have to convert 12mm to its corresponding value in cm. Let's remember that 1cm is 10mm; thus, 12mm is 1.2cm. Let's apply the formula.


B=4\cdot1.2=4.8\operatorname{cm}
