Final answer:
The missing measures depend on the context or problem mentioned.
Step-by-step explanation:
The missing measures in this question depend on the specific context or problem being referred to. Let's go through each option:
a) Length and Width: These missing measures are typically related to the dimensions of an object or a shape, such as the length and width of a rectangle.
b) Area and Perimeter: These missing measures are related to the size and boundary of a shape, such as the area and perimeter of a rectangle.
c) Radius and Diameter: These missing measures are specific to circles and refer to the length from the center to the edge (radius) and the length across the circle passing through the center (diameter).
d) None of the above: If the context or problem doesn't involve any of the above situations, then none of these missing measures would be relevant.
Therefore, the missing measures depend on the specific problem or context, and it could be any of the options mentioned above, or none of them.
