# Rectangle Functions

## Objective

To get experience writing a functions.

## Task

For this lab you will write a program which calculates a few properties of
rectangles. Each will be done with a separate function. The three functions
you should write are:

`area`

This function should take the height and width of the rectangle and return the
area of the rectangle. which is the product of the two.

`perimeter`

This function should take the height and width of the rectangle and return the
perimeter, which is the sum of all four sides.

`isSquare`

This function should take the height and width and return a boolean indicating
whether or not the rectangle is also a square.

## Calling Code

Use the following code to fill out the rest of the program:

```
height = int(input("Enter the rectangle's height: "))
width = int(input("Enter the rectangle's width: "))
print("The area is", area(height, width))
print("The perimeter is", perimeter(height, width))
if isSquare(width, height):
print("This rectangle is a square.")
else:
print("This rectangle is not a square.")
```

You shouldn't need to change this at all. If you write the three functions
above this, then it should work.

## Example Run

Here is an example run of this program. Be sure to also test case where the
rectangle *is* a square to make sure that function is working correctly.

Enter the rectangle's height: **7**
Enter the rectangle's width: **5**
The area is 35
The perimeter is 24
This rectangle is not a square.

## Submitting

When your program is finished, email the .py file to ifinlay@umw.edu.
