Answer:
8x³ + 27
Step-by-step explanation:
Formula: [tex]\tt{Area \: = Length \times Width}[/tex]
- Solve it using distributive property
A = l × w
A = (4x² - 6x + 9)(2x + 3)
A = 4x²(2x + 3) - 6x(2x + 3) + 9(2x + 3)
A = 8x³ + 12x² - 12x² - 18x + 18x + 27
A = 8x³ + 27
Therefore, 8x³ + 27 is the area of a rectangle.
