PreviewCalculating perimeter is actually really easier than it looks because all you are doing is adding lengths of all sides of shape.To find a perimeter you need a two-dimensional shape. So let's say we have to find the perimeter of a lawn which is in the shape of a rectangle.To find the perimeter we need measurements and so let's say that the measure of two sides are 21 feet and the the other two sides are 32 feet. Now to find the perimeter we need to add all the measurements like this:
21 32 64
+21 + 32 +42
----- ------ ------
42 64 106
So now we know that the total answer is 106 feet that is the total perimeter.
Now try some of these and make sure to watch the video on YouTube.
