Let's work out the area of this rectangle.
The height of the rectangle is 6cm and the width is 4cm.
Using height x width = area
6cm x 4cm = 24cm²
The total area of the rectangle is 24cm² .
What is the area of this shape?
To work out the area of this shape may look a little more complicated but it's not.
You can split the shape into two different rectangles, work out the area for each rectangle and then add them together to find the total area of the shape.
area = height x width
For the orange rectangle: 4cm x 3cm = 12cm²
For the yellow rectangle: 2cm x 3cm = 6cm²
For the total area of the shape: 12cm² + 6cm² = 18cm².
The answer is 18cm².
To work out the area of a square or rectangle:
height x width = area
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.
