This activity allows students to practice finding the perimeter and area when the interior lines can't be seen. These types of questions are common on standardized tests where students have to estimate or imagine that the lines are there in order to count the area accurately. The second page can be printed double-sided so that students who finish early have a challenge. The challenge is to draw different variations of rectangles that all have a perimeter of 24, then to determine which one has the greatest area.
