Area:
Calculating area:
To work out the area of a square or rectangle, multiply its height by its width.
If the height and width are in cm, the area is shown in cm². If the height and width are in m, the area is shown in m².
A square with sides of 5 m has an area of 25 m², because 5 × 5 = 25.

Calculating perimeter:
The perimeter is the distance all the way around the outside of a 2D shape.
To work out the perimeter, add up the lengths of all the sides
The perimeter of this shape is 10 + 10 + 6 + 6 = 32
