Question

The Function will be able to calculate the area of the following polygons: Right triangles, Rectangles, and regular polygons.

It will do so by taking the following inputs:
- numSides – a double of the number of sides the polygon has
- sideLengths – a double of the length or lengths of sides of the polygon  

The program should determine if the inputs are formatted properly. The rules are: 
- numSides must be a positive integer number with values greater than or equal to 3.
- When numSides is 3 or 4, sideLengths can either be a scalar or an array with two values.
- When numSides is greater than 4, sideLengths must be a scalar.  

To determine if a number is an integer, you can use the rem function. rem returns the remainder of whole
number division. It has the following syntax: remainder = rem(numerator, denominator);


Where remainder is the remainder of numerator/denominator. To use this to find whether a
number is an integer, use rem in the following way: remainder = rem(number, 1);


When number is an integer, remainder will be 0. Otherwise, remainder will be nonzero.
To determine how many numbers are contained in an array, use the length function. The length
function has the following syntax: N = length(arrayName);

Where N is the number of elements (i.e. the number of numbers) contained in array arrayName.


3 different ways of calculating area of your polygon.
- When numSides is 3 and sideLengths is an array with two numbers, you will calculate the
area of a right triangle, where the two numbers inside of sideLengths are the sides of the
triangle that are not the hypotenuse.  

When numSides is 4 and sideLengths is an array with two numbers, you will calculate the
area of a rectangle where the two numbers inside of sideLengths are your two different
lengths for the sides of your rectangle.  

In all other valid cases, the scalar sideLengths is the length of all sides of your polygon, no
matter what numSides is.
