AREA OF RECTANGLE

Product of a Polynomial to a Polynomial

The length of a rectangle lot is (b² + 3b + 2) and its width is (b + 2). What is the area of the lot?

Formula:

Solution:

• A = LW
• A = (b² + 3b + 2)(b + 2)
• A = b² (b + 2) + 3b (b + 2) + 2 (b + 2)
• A = b³ + 2b² + 3b² + 6b + 2b + 4
• A = b³ + 5b² + 8b + 4

Answer:

• C. b³ + 5b² + 8b + 4
