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

1. Find the area and perimeter of the trapezoid below.

   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. Find the area and perimeter of the trapezoid that is similar to this one, but has been reduced by a linear scale factor of $\frac { 1 } { 3 }$.
