Find the area of the shaded region<br> below.<br> Give your answer in terms of T.<br> 12m<br> 5m
Step2247 [10]

The area of the shaded region is [(169π/4)-60]m².

  • The length of the rectangle is 12 m.
  • The breadth of the rectangle is 5 m.
  • The area of the rectangle = length * breadth.
  • The area of the rectangle = 12 * 5
  • The area of the rectangle = 60m²
  • Let h be the diagonal of the rectangle.
  • Using the Pythagorean theorem,
  • h² = 12² + 5²
  • h² = 144 + 25
  • h² = 169
  • h = √169
  • h = 13
  • The diagonal of the rectangle is also the diameter of the circle.
  • Let r be the radius of the circle.
  • 2r = 13
  • r = 13/2m
  • The area of the circle is πr².
  • The area of the circle = π(13/2)²
  • The area of the circle = (169π/4)m²
  • The area of the shaded region equals the area of the circle minus the area of the rectangle.
  • The area of the shaded region = [(169π/4) - 60]m²
