SAMPLE RUNS:

RUN #1:

Created rectangle r1 with width 1; height 2

Created parallelpiped p1 with width 1; height 2; length 3

Enter an integer for the width of rectangle r2 >

1

Enter an integer for the height of rectangle r2 >

2

Created rectangle r2 with width 1; height 2

Rectangle r2 is equal to r1

Rectangle r1 perimeter is 6

Rectangle r1 area is 2
