Can you find the perimeter of a rectangle where not all the lengths are marked?
Find the perimeter of the rectangle shown.
In this video, we deconstruct and reconstruct a rectangle. If we know the perimeter and one of the side lengths we can work out the other.
Find the missing side length of the rectangle shown.
A part of the perimeter can be considered a fraction of the perimeter.
Consider the square below:
If you start at point A and travel clockwise \dfrac12 of the way around the square, where do you end up?
If you start at point A and travel clockwise \dfrac14 of the way around the square, where do you end up?
selects and uses the appropriate unit and device to measure lengths and distances, calculates perimeters, and converts between units of length
