1-50.

For each of the shapes formed by algebra tiles below:

  • Sketch and label the shape on your paper and write an expression that represents the perimeter.

  • Simplify your perimeter expression as much as possible.

  1. 4 positive algebra tiles, all aligned on the bottom: 3 vertical X tiles with a unit tile connected on the right.

  1. 6 positive algebra tiles: 1, y squared tile aligned with 1, XY tile on the right. At the top right corner, & at the bottom left corner, each has 2 unit tiles, one on the horizontal, & one on the vertical, so they have a touching vertex, with the corner of the large tile.

2 positive algebra tiles: A vertical X tile connected on the right with a unit tile aligned on the bottom.

Start by labeling the sides.

2 positive algebra tiles: A vertical X tile connected on the right with a unit tile aligned on the bottom. The sides of the tiles are labeled as follows starting on the top left and going clockwise: 1, (X minus 1), 1, 1, 2, X
