The sum of the interior angles is 360
Answer:
17
Step-by-step explanation:
5x3=15, that's the area of the larger square. Next, 2x1=2 is the area of the smaller one. (3-2=1 and 7-5=2)
17
Answer:
r ≈ 2.07
Step-by-step explanation:
Using the formula
C=2πr
Solving for r
r= C/2π = 13/2π ≈ 2.06901
Use the distance formula to find the length of the sides, then add them up to find the perimeter.

For points in the form of (x1, y1), (x2, y2).
(-1, 2), (3, 1)




(3, 1), (7, 2)




(7, 2), (-1, 2)




So the perimeter will be:
Another form of (x + 1) ^2 is (x +1)(x + 1)
