problem_activity: Problem 1
a.   Create as many rectangles as you can with a perimeter of 16 units. Find the area of each rectangle that you found. Then record the length, width, perimeter, and area of each rectangle in the table below:
| **                Length (units)               ** | **                Width (units)               ** | **                Perimeter (units)               ** | **                Area (square units)               ** |
