Algebra tiles are square and rectangular tiles used to represent algebraic principles. The small square tiles represent an area of 1. The small square tiles are unitary; the small tiles define one square unit.
]The rectangular tiles represent and area of x. The short side has a length of 1, and the long side has a length of x. Using the formula for the area of a rectangle (A = l x w), A = 1·x = x, the area of a rectangular tile is x.
The large square tiles represent an area of x^{2}. Each side has a length of x. Using the formula for the area of a square (A = s^{2}), A = x^{2}. The area of the large square tiles is x^{2}.
