pdf Combining Like Terms - Perimeter Of Triangles

This worksheet reinforces combining like terms by placing algebraic expressions in a geometric context. Students are given triangles with side lengths written as algebraic expressions and are asked to write a single expression that represents the perimeter of each triangle. To do so, they must add all side lengths and combine like terms correctly, then simplify the result.

By connecting perimeter to algebraic expressions, students practice organizing terms, identifying like terms, and simplifying expressions in a meaningful application. The problems require careful attention to coefficients and variable terms, helping students strengthen algebraic reasoning while working with a familiar geometric concept.
