Expression for the area of the window is 4x² + 6x - 4

Step-by-step explanation:

  • Step 1: Given width of the window = 2x - 1. So, length = (2x-1) + 5 = 2x + 4. Find area of the window.

Area of the window = length × width

                                 = (2x + 4) × (2x - 1)

                                 = 4x² - 2x + 8x - 4

                                 = 4x² + 6x - 4
