Explore Perimeter with Missing Sides
Turn up the complexity level in your perimeter lessons with this set of perimeter practice problems that require students to calculate the missing side.
This two-page perimeter with missing sides worksheet contains eight different word problems. Students must use their knowledge of perimeter to calculate the missing side of the shape described.
For example: The perimeter of Mr. Manwell’s shed is 6 meters. The length of the shed is 2 meters. What is the width?
Students are required to show their work. They will need to draw the shape, add the dimensions and then show the calculation required to arrive at the answer.
Questions involve a combination of metric and customary units to ensure that students become familiar with both systems of measurement.
This perimeter worksheet with missing sides downloads as a quick-print PDF or an editable Google Slides file. Answers are also included in both downloads.
