How to Measure Perimeter and Area
Perimeter is the length of all the sides of a shape put together.

Area is the amount of surface area INSIDE all of the sides of the shape.
To find the area of a square or rectangle, you just multiply the WIDTH by the LENGTH.
When you write the answer, you have to measure in square cm, square m or square km. We do this because we need to imagine covering the surface with squares of the same size, in the same unit as the length and width.
For example, I have a rectangle that has sides that are 4cm and 6cm long.So my area is the L x W which is 4 x 6. The answer is 24 square centimetres. I would need 24 little cm squares to cover the whole shape.

It is important to write square cm with a little floating two, see below.

You would then write square metres as m2 and square kilometres as km2.

The number 2 is a clue that area uses TWO dimensions, those being length and width.

The length and width can sometimes be called height and breadth.
