Finding perimeter when a side length is missing. So 2 units long times 5 sides is going to be 10 units. If you’re seeing this message, it means we’re having trouble loading external resources on our website. Add this document to collection s. We want to make sure that we only go to where we started and we don’t double count.

So let’s say we start up here. To log in and use all the features of Khan Academy, please enable JavaScript in your browser. Transformations Worksheets This section contains all of the graphic previews for the Transformations Worksheets. Pythagorean Theorem Geometry Worksheets. So all of the sides have length 2. Discuss how to find the perimeter of polygons based on what you know about their shape and size.

And by definition, a square– all of its sides are equal. So this is 1 plus 2 plus 3 plus 1 plus 3 plus 1 plus– what is this– 5 plus 2 plus 4 plus 2. Look for correct answers and anything that may need further explanation.
