Sketch the shape made with algebra tiles below on your paper. Then answer parts (a) and (b) below. .

1. Find the area of the shape.

   Hint (a):

   Sum the areas within the shape to find the area of the entire shape.

   More Help (a):

   $x^2 + x^2 + x + x = ?$

   Answer (a):

   $2x^2 + 2x$

2. If the algebra tiles were rearranged into a different shape, how would the area change?

   Hint (b):

   Area is the number of square units needed to fill up a region on a flat surface.

   Answer (b):

   No, the area would not change because the tiles are simply rearranged. This rearrangement of the tiles does not affect the area.
