Step-by-step explanation:
Add it all together.
Answer:
B. 2 in.
Step-by-step explanation:
First, put the two perimeters together to form a fraction.
192/48, which can simplify to 4/1
Now, following the order in which you put the perimeters (I used C/D,) set it equal to the sides.

Now, cross multiply. (multiply 1 and 8, 4 and x.)

Now, solve.
x=2 inches.
2 An angle in a regualr quadrilateral = 90 degrees
3. if exterior angle = 40 degrees then the number of sides in the plygon
= 360/40 = 9 sides
So its a nonagon.
