### Perimeter at a glance

The perimeter of a 2D shape is the distance all the way around the outside of it. For the perimeter of a rectangle or other quadrilaterals such as a rhombus or a parallelogram we need to add up all of the side lengths to find the total. The process is the same for irregular shapes and for the perimeter of polygons such as pentagons or hexagons.

Sometimes, students are required to measure the length of the sides from an accurately drawn diagram and then calculate the perimeter as above. It is therefore important that students can work confidently with metric units and decimals.

Compound shapes (shapes made from two or more simple shapes) can be more tricky. For example, if finding the perimeter of rectilinear shapes, it is important that students carefully identify the outside edges of the shape and don’t just add up all the side lengths they can see. More complex problems could include using subtraction to find a missing side length, or to use 2D shape properties to work out the side lengths and then find area. Perimeter word problems could require students to calculate the length of a fence or boundary.

Looking forward, students can then progress to additional geometry worksheets, for example an area of a rectangle worksheet or angles in polygons worksheet.
