Answer:
9x² - 12xy + 4y²
Step-by-step explanation:
Given,
Side of the square = 3x -2y
We know that area of a square is a² { where a is the side }
So,
Area = (3x - 2y)²
⇒ (3x)² - 2(3x)(2y) + (2y)² { Using identity (a - b)² = a² - 2ab +b²}
⇒ 9x² - 12xy + 4y²
∴ The are of a square whose side is 3x - 2y is 9x² - 12xy + 4y²
