Exploring Area and Perimeter with Algebra Tiles

What is the area of a unit tile?

• 0

• X squared

• 1

• X

How is the perimeter of an X tile calculated?

• 1 + X

• 2X + 2

• X + X

• 4X

What is the perimeter of a shape made of three unit tiles?

• 12

• 8

• 3

• 6

If a shape consists of 1 X tile and 2 unit tiles, what is its area?

• X + 2

• 2X + 1

• 3X

• X squared + 2

For a shape with 2 X tiles and 1 unit tile, what is the correct expression for its area?

• X + 1

• 3X

• 2X + 1

• 2X squared

What is the perimeter of a shape that includes an X squared tile, an X tile, and a unit tile?

• 4X + 4

• 5X + 1

• 3X + 4

• 4X + 3

How do you calculate the perimeter of a shape with 1 X squared tile, 2 X tiles, and 2 unit tiles?

• 5X + 2

• 6X + 2

• 4X + 8

• 4X + 6

In a complex shape where part of an X tile is covered, how is the missing piece represented?

• X + 1

• X

• X - 1

• 1 - X

What is the area of a shape that has 1 X tile and 1 unit tile?

• X squared

• 2X

• 2

• X + 1

If a shape's perimeter includes 'X minus 1', what does it indicate?

• The shape is incomplete

• An extra unit tile is added

• An error in calculation

• An X tile is partially covered
