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!
