Same Perimeter, Different Area Word Problems
Have your students mastered the basic concepts of perimeter and area? If so, they may be ready for more challenging maths problems where they have to use multiple operations to solve a problem. These multi-step word problems will give your students an opportunity to answer questions where they have to use the perimeter of one object, determine the missing side length of another object, and then calculate the area.
With this worksheet, students will have the opportunity to practise solving 8 problems where 2 objects have the same perimeter but different areas. Questions are similar to the following:
James’ sandpit is 4 metres long by 2 metres wide. Tommy’s sandpit has a length of 3 metres. If James and Tommy both have sandpits with the same perimeter, what are the areas of the two sandpits?
Samantha and Carly have playrooms of the same perimeter but different areas. Carly’s playroom is 6 metres long by 8 metres wide. One of the walls in Samantha’s playroom is 5 metres long. Who has the playroom with the larger area?
