- Perimeter is the distance around a two-dimensional shape. Example: the perimeter of this rectangle is 7+3+7+3 = 20 Example: the perimeter of this regular pentagon is: 3 + 3 + 3 + 3 + 3 = 5×3 = 15 The perimeter of a circle is called the circumference: Circumference = 2 π × radius

The perimeter of a shape is the total measurement of all the edges of a shape e.g. a triangle has three edges, so its perimeter is the total of those three edges added together. The perimeter of a square is easy to calculate if one side is given as all sides are the same length; the perimeter of a square with side length 5cm is 20cm, because 5 x 4 ...
When measuring the perimeter of more complex shapes, children could be encouraged to highlight each edge as they add it together to ensure they don’t miss any out.
Perimeter is taught in KS2. Children begin by learning to measure the perimeter of simple 2-D shapes in Year 3. This is built on in Year 4, where children measure and calculate the perimeter of a rectilinear figure (including squares) in centimetres and metres. In upper KS2, children measure and calculate the perimeter of composite rectilinear shap...
Perimeter is most closely linked to properties of shapes, 2D shapes and 3D shapes, and is one of the most basic and important parts of KS2 Geometry. A good understanding of how to calculate the perimeter of a shape is needed before children can begin to learn more complex geometric ideas such as area and volume. Wondering about how to explain other...

Here are some shapes on a 1cm square grid. a) What is the perimeter of shape A? b) Which shape has the smallest perimeter? (Answer: a) 14cm b) D) 4. Megan says, ‘If two re...
What is the perimeter of a shape? The perimeter of a shape is the distance around its edge. Example. An ant walks all the way around the edge of a rectangle, measuring \(3~cm\) by...
What children will learn is that the perimeter of a circle is also called ‘circumference’. Because it’s difficult to directly measure the distance around this shape, there is a formula, which is followed to calculate the circumference. Here’s the formula with an explanation of what each symbol stands for: C = 2πr.
Perimeter is the distance around a two-dimensional shape. Example: the perimeter of this rectangle is 7+3+7+3 = 20. Example: the perimeter of this regular pentagon is: 3 + 3 + 3 + 3 + 3 = 5×3 = 15. The perimeter of a circle is called the circumference: Circumference = 2 π × radius.
What Is the Perimeter? The perimeter of a shape is the measurement of the length of the outline of the shape. To find the perimeter of a shape, you add together the length of all of its edges. Children might be given the perimeter of a shape and asked to work out the length of unlabelled edges.
Nov 13, 2020 · The perimeter of a shape is the total of the length of the outside edge of the shape. It can be found by adding up the lengths of all the individual edges. Page Contents. What is the perimeter? So now that you know what the perimeter is, let’s visualise it: How do you teach kids about the perimeter? How to find the perimeter of a triangle:
