Perimeter is the length around a closed 2-D shape.
The perimeter of the rectangle
is 22 cm.

Which shapes can we measure the perimeter of?
A and D
Have a think
I think I can find the perimeter of this shape because I can see that it must be a rectangle.
I don’t think we can just predict that it must be a rectangle.
It could be several other shapes, look!
Wow Eva! So that means that we can only find the perimeter of closed shapes.
That’s right Tiny! There can’t be any gaps!

Draw a quadrilateral with a perimeter of 20 cm.
A quadrilateral is a 4-sided 2-D shape.
