How many subsets of a set with 100 elements have more than one element?

The answer to your question is the number of all of the subsets minus the number of subsets with just one element.

had do you find the perimeter and the area

whats the measurment of b

To find the perimeter of a shape, you need to know the lengths of all its sides. Simply add up the lengths of all the sides to calculate the perimeter.

To find the area of a shape, it depends on the shape itself. Different shapes have different formulas for calculating their area. For example, the area of a rectangle is given by multiplying its length by its width.

Without specific information about the shape, it is not possible to provide an accurate method for calculating either the perimeter or the area.

Similarly, without context or additional information, I cannot determine the measurement of "b." Please provide more details or clarify your question.
