Question

21. Find the perimeter of the parallelogram. On points (8,13)(8,18)(13,3)(13,15)

Answer 1

We find the perimeter as follows:

`p=\sqrt[]{(18-13)^2+(8-8)^2}+\sqrt[]{(3-18)^2+(13-8)^2}+\sqrt[]{(15-3)^2+(13-13)^2}+\sqrt[]{(13-15)^2+(8-13)^2}`

That is equal to:

`p=38.19655311`

We have that the perimeter of the parallelogram is approximately 38.2 units.

We determined it by finding the distance between the points and adding them.
