When measuring the sides of a 2D object, what attributes should be primarily considered?

Length and height
Length and width
Width and area
Height and depth

The correct answer is: Length and width

The most relevant attributes for measuring the sides of a 2D object are length and width. In the context of 2D shapes, these two dimensions are essential because they define the size and shape of the object on a flat plane. Length typically refers to the measurement of the longer side of the shape, while width refers to the measurement of the shorter side. Considering length and width allows for a complete understanding of the object's dimensions, facilitating tasks such as calculating perimeter and area. Other combinations, such as height and depth, pertain more to three-dimensional objects, while width and area also do not align with the direct measurement attributes required for 2D geometry. Thus, focusing on length and width gives a clear and accurate representation of a 2D object's size.
