Answer:
C = a² + 2ab + b²
Step-by-step explanation:
From the diagram above,
Let the dimension of the square be
A (length) = (a + b) and B (breadth) = (a + b).
Area of the square is A*B
A * B = (a + b) * (a + b)
Area = a² + ab + ab + b²
Area = a² + 2ab + b².
Therefore the expression that defines the area of the square is a² + 2ab + b².
