The two polygons at right are similar.

1. Determine the value of $x$. Show all work.

   Hint (a):

   Set up a proportion to determine the value of $x$.

2. Calculate the area of each polygon.

   Hint (b):

   Divide each polygon into smaller, easier polygons, then calculate the areas.

   

   Answer (b):

   area of smaller figure: $56$ in²
   area of larger figure: $350$ in²
