Answer:
P = 25.64
Explanation:
Perimeter means the distance around the outside of a shape. If you put points on a graph you can see what you are dealing with. Also, distance formula allows you to calculate the distance between points just without a drawing. But distance formula is just a short cut for pythagorean theorem. You can clearly see the lengths of the sides of right triangles for pythagorean theorem when you have a sketch. The calculations are the same. See image.
