Answer:
D. 8*x
Step-by-step explanation:
Hello there! A regular octagon has eight sides with the same extension. The perimeter is the addition of each of them. If each side is x units length, then x + x + x + x + x + x + x + x = 8*x is its perimeter.

24/32=3/4
A(3,-2) ; B(6,-2)
AB = 3 units
B(6,-2) ; C(6,5)
BC = 7 units
Area of rectangle = length * width
= AB * BC
= 3 * 7
= 21 square units
