Question

Find the perimeter of the shaded region. Round your answer to the nearest hundredth.

Answer 1

• 21.42 units

-------------------

The shaded region has two sides of 6 units and another two sides are quarter- circles with a radius of 3.

The perimeter is the sum of four sides:

• P = 2*6 + 2*(1/4)*2πr
• P = 12 + 3.14*3
• P = 12 + 9.42
• P = 21.42
