# MATHS HELP – PERIMERTER

January 3rd, 2018

- A perimeter is the distance around a shape.
- To find out the perimeter you need to add up the length of the sides.

*example:*

Find the perimeter on the shape on the right

Just add up the length of the sides of the

shape – try not to miss any.

# 11 + 8 = 19 + 13 = 32cm

## rectangles

When doing rectangle you are normally given 2 sides. This is because that the opposite side is always the same length.

# 12 + 12 = 24 9+9 = 18 18 + 24 = 42 cm
