Shaded areas ( What is the area of the shaded region? )

119.43 cm²

Step-by-step explanation:

The shaded area (A) is calculated as

A = area of rectangle - area of circle

   = (11 × 12) - π × 2²

  = 132 - 4π

  ≈ 119.43 cm² ( to the nearest hundredth )

Step-by-step explanation:

as we can observe ,

length of rectangle and breadth = 12 cm and 11 cm

now ,area of rectangle = l×b =12 cm × 11cm =132 cm ^2

now ,area of circle = 22/ 7 × 2cm×2cm = 12.57cm^2 Now,

area of shaded region = area of rectangle _ area of circle =132cm^2 _ 12.57cm^2 =129.43cm^2
