Ratio of perimeters of smaller solid to larger solid = ratio of the sides of the corresponding sides of smaller solid and larger solid .
Let the perimeter of smaller solid =x and perimeter of larger solid =y. Therefore
[tex] \frac{x}{y} = \frac{52}{68} [/tex]
[tex] \frac{x}{y} = \frac{13}{17} [/tex]
Therefore the answer is 13/17 .
