MATHS HELP – PERIMERTER

1.  A perimeter is the distance around a shape.
2. 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
