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

The sector area is = pi * r^2 (circumference/360). Do the work inside the () first and then multiply by pi r^2
If you would like to know the Susan's pay for the week, you can calculate this using the following steps:
P = B * h
P ... the pay
B ... the base pay
h ... the number of hours worked
B = $6.35
h = 28 hours
P = B * h = $6.35 * 28 hours = $177.8
Susan's pay for the week would be $177.8.
