What is the peremiter of the retangle shown on the coordinate plane to the nearest tenth of a unit

To calculate the perimeter, consider each side separately. Since this is a rectangle, you have 2 pairs of sides of equal length, so you just have to calculate the length of one of each pair of sides and then double each and add them to find the perimeter.

Top side: If you look carefully, this side is really the hypotenuse of a triangle that is 4 units tall and 8 units long. Using the Pythagorean Theorem, you can calculate the length of the hypotenuse to be 8^2 + 4^2 = c^2 --> c = 8.9

Left side: Just like the top side, this side is the hypotenuse of a triangle that is 4 units tall and 2 units long. Pythagoras again: 4^2 + 2^2 = c^2 --> c = 4.5

Since you have two of each side that are the same length, double each and add for the final perimeter: 8.9*2 + 4.5*2 = 26.8
