8-86.

On your paper, sketch the shape made with algebra tiles at right. Then answer parts (a) and (b) below. 8-86 HW eTool (CPM)

1. Find the area of the shape.

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

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

$2x^2+2x$

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

• 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.
