Answer:

  • 8y + 16

Step-by-step explanation:

The shaded area is the difference of the large and small squares.

<u>Area of large square:</u>

  • A(l) =  (y + 4)²

<u>Area of small square:</u>

  • A(s) = y²

<u>Shaded area:</u>

  • A = A(l) - A(s)
  • A = (y + 4)² - y² = y² + 8y + 16 - y² = 8y + 16
