Variables Exercises: Part A

#1. MyRectangle class.

a) Create a class called MyRectangle

b) Build your main method

c) Declare two floating point variables named length and width and assign 
the value 5.2 to length and 6.1 to width

d) Now, declare a floating point variable called areaOfRectangle and 
make it equal to the length times the width.  In java, we use * to 
perform mulitplication

e) Finally, print out the area for our rectangle (it should show 31.72).

f) Change the values assigned to length and width.  If you've written 
your program correctly, you should always get the correct area of the 
rectangle!


HINT 1 - Remember that we let the variables do the work for us.  Once
 we've assigned a value to a variable, we can just use the variable 
 name whenever we want to use that value.


#2. Modify MyRectangle.java

Change the output of your program so that, instead of just showing the 
area as a number like 31.72, your program will output a more user-friendly 
output such as:

The area of the rectangle with a width of 30 cm and a height of 2 cm is 
60 square cm.

HINT: Try not to do calculations inside your print statement.  
Use a well-named String variable and output that.
