Answer:

  • Option A

Step-by-step explanation:

The area outside of the semicircle is the difference of the areas of the rectangle and the semicircle.

Area of rectangle:

  • A₁ = w(w + 5) = w² + 5w

Area of the semicircle:

  • A₂ = 1/2*πd²/4 = 1/8*πw²

The area we are looking for is:

  • A = A₁ - A₂
  • A = w² + 5w - 1/8πw²

Correct choice is A
