There are more shapes that you could calculate the area for such as pentagons and hexagons but these are the most important ones.
Calculating Perimeter of Shapes
You also have to be able to calculate the perimeters of shapes. Again there are formulas which will help you.
To find the perimeter of any of these shapes, add up the lengths of all the sides. If you are dealing with regular shapes (eg: pentagon), you can also multiply one side length by the number of sides.
Volume & Surface Area
Another topic that you should try is to find volumes and surface areas of 3D shapes. You can also have a look in our library to see if you find another topic that you would like to study. Please share this page if you like it or found it helpful!
