The ratio of the perimeters are the same as the ratio of the sides.
[tex]\dfrac{28}{8}[/tex]
That's the ratio of the sides. The ratio of the perimeter will be the same. Now, just simplify the fraction.
[tex]\dfrac{7}{2}[/tex]
That's the answer to part a.
Now, just square this fraction to get the ratio of the area.
[tex](\dfrac{7}{2})^2=\dfrac{49}{4}[/tex]
The answer is the second choice.
