Area of rectangle = h X w

Area is the space inside a shape's outline and is measured in squares.

If there is a grid you can work out the area of a rectangle by counting the number of squares covered by the shape.

For all rectangles and squares, whether there is a grid or not, you can work out the area by multiplying the width by the height.

For Example.

A rectangle that is 3cm wide and 4cm high will be 3 X 4 = 12cm².

If the shape is measured in mm your answer will be mm² if the shape is measured in inches your answer will be inches² and so on.
