Both charms are "similar".
And notice one diameter is 1, the other is 4, the diameters are on a ratio of 1:4 then, and so both figures are on a ratio of 1:4.

Area = length x width
Perimeter = 2(l + w)
Let's imagine one of the sides is 6. The other side would have to be two, and the perimeter would be 16.
If one of the sides is 4, the perimeter would be 14.
If one of the sides is 1, the perimeter would be 26.
