MP = P - M = (0, 5) - (5, 6) = (0-5, 5-6) = (-5, -1) |MP| = √((-5)^2 + (-1)^2) = √(25+1) = √26
I think you add all of the sides for example add 5+5+10.6+10.6= 31.2 that would be your answer.
Answer:
C = πd = 14π = 14 * 3.142 = 43.988
Note that the Area of a rectangle is given by
Area = LB
Where L is the Length (the longer side) and B is the Breadth (or Width which is the shorter side).
From the image, L is (x+6).
Also from the image, B is (x+2)
This implies:

Open up the bracket by multiplying both terms:

Since the question says to leave it in polynomial form, that is your answer. Hope I helped? ☺️
