Area and Perimeter
In this worksheet, further explore the relationship between area and perimeter by trying to find the box with an area of 25m2 that will have the largest perimeter. It then becomes and exploration of data and tables, and can even be turned into a graph that will introduce parabolic lines. This resource is part of a larger unit where students are introduced to the concept of calculating the area
of rectangles and triangles, using metric units.
