List all the types of algebra tiles.

Explain the area and dimensions of each type of algebra tile.

Why could the arrangement of algebra tiles into a rectangle be described as an area problem?

Describe what a rectangle composed of algebra tiles would look like for (x+4)(x+3).

Before the expanded product is simplified, (x+4)(x+3) = x² + 4x + 3x + 12. How are 4x and 3x represented in the algebra tiles rectangle?
