To work out area it depends on the shape. Here are some formulas for some shapes:
Square
Length x Length = Area
This means you find the length of the side and multiply it by itself again.
Rectangle
Length x Width = Area
This means you find the length of one side then you find the width of another and multiply them.
Triangle
Base x Height ÷ 2
This means you find the length of the base and you multipy it by the height. Then you divide the by 2.
Trapezium
(a + b) x Height ÷ 2
This means you find the top part of the trapesium (a) and you mulitiply iy by the bottom part of the trapezium (b). You them mulitply the by the height of the trapezium. After that, you divide the by 2.
Parallelogram
Base x Height
This means you multiply the base of the Parallelogram by its height.
Circle
Pi x r2 or Pi x d
Pi x r2 : This means you find the radius of the circle, square it and multiply it by Pi.
Pi x d : This means you find the diameter of the circle and multiply it by Pi.
