Perimeter of Polygon A is 128

Perimeter of Polygon B is unknown

Answer 1

80

Explanation:

Is the correct answer :)

Answer 2

`\bf \textit{ratios relations for similar figures} \\\\\\ \begin{array}{cccllll} side&area&volume\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ (s)/(s)=(s)/(s)&(s^2)/(s^2)=(area)/(area)&(s^3)/(s^3)=(volume)/(volume) \end{array}\\\\ -----------------------------\\\\`


`\bf thus \\\\\\ \begin{array}{llll} \cfrac{\textit{polygon A}}{\textit{polygon B}}\qquad &\cfrac{24^2}{15^2}=\cfrac{128}{x} \end{array}`

solve for "x"
