6-86.
  1. On your paper, sketch the shape made with algebra tiles at right. Then answer parts (a) and (b) below. 6-86 HW eTool (CPM). Homework Help ✎

    1. Find the area of the shape.

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

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

x² + x² + x + x = ?

2x² + 2x

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

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