# What’s the perimeter?

Posted by on October 17, 2016

We’ve had the metre sticks and rulers out in Year 3 this week.  We have been measuring the perimeter of large shapes in the hall and small shapes in the classroom.  Have a go at these questions at home.

Challenge: Can you write the instructions of how to work out the perimeter of a shape?

4cm + 4cm + 2cm + 2cm = 12 cm 3cm + 3cm + 3cm + 3cm = 12 cm 4cm + 4cm + 3cm + 3cm = 14cm 6cm + 6cm + 2cm+ 2cm = 16cm
