Answer:
second option
Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b, then
ratio of areas = a² : b²
(a)
ratio of sides = [tex]\frac{28}{8}[/tex] = [tex]\frac{7}{2}[/tex]
ratio of perimeters is the same as ratio of sides = [tex]\frac{7}{2}[/tex]
(b)
ratio of areas = 7² : 2² = 49 : 4 = [tex]\frac{49}{4}[/tex]
