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:
{"table": [{"_attributes": {"align": "center", "class": ["table", "table-bordered"], "style": "table-layout:fixed; width:90%"}, "tbody": [{"tr": [{"td": [{"_attributes": {"style": "background-color:#eeeeee; text-align:center"}, "strong": [{"_value": "Length (units)"}]}, {"_attributes": {"style": "background-color:#eeeeee; text-align:center"}, "strong": [{"_value": "Width (units)"}]}, {"_attributes": {"style": "background-color:#eeeeee; text-align:center"}, "strong": [{"_value": "Perimeter (units)"}]}, {"_attributes": {"style": "background-color:#eeeeee; text-align:center"}, "strong": [{"_value": "Area (square units)"}]}]}, {"td": [{}, {}, {}, {}]}, {"td": [{}, {}, {}, {}]}, {"td": [{}, {}, {}, {}]}, {"td": [{}, {}, {}, {}]}, {"td": [{}, {}, {}, {}]}, {"td": [{}, {}, {}, {}]}, {"td": [{}, {}, {}, {}]}]}]}]}
b.   What do you notice about the rectangles you created? What do you wonder?
Problem 2
