Use what you know about similar figures to complete the following tasks. 

1. What are the area and perimeter of the trapezoid at right?

   Hint (a):

   Do not assume the trapezoid is isosceles even though it looks like it.
   Start by solving for $x$ in the diagram, then solve for $y$, then calculate the length of the unknown side of the trapezoid.

   

   Answer (a):

   Area $= 42$ square units

2. What are the area and perimeter of a trapezoid that is similar to this one but reduced by a linear scale factor of $\frac { 1 } { 3 }$?
