Answer:
x² + 10x + 25 units²
Step-by-step explanation:
The area of a square is the length of the side squared, that is
area = (x+ 5)² = (x + 5)(x + 5)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x + 5) + 5(x + 5) ← distribute both parenthesis
= x² + 5x + 5x + 25 ← collect like terms
= x² + 10x + 25
