Final answer:
The area of a square with side length (3x-2) feet is calculated as (3x-2)², which simplifies to 9x² - 12x + 4 square feet.
Step-by-step explanation:
The area of a square is calculated by squaring its side length. To determine the area of a square with side length (3x-2) feet, we follow the mathematical equation for area, which is side × side or side squared. Therefore, the area of this square is (3x-2)² square feet.
When calculating, we apply the exponent to both terms inside the parentheses: (3x)² - 2(3x)(2) + (2)², which simplifies to 9x² - 12x + 4 square feet as the final area.
