The area and perimeter is needed

Perimeter = 30 + 4  ≈42.56 cm

Area = 88 - 8 ≈ 62.88 cm^2

Step-by-step explanation:

area of rectangle = 11* 8 = 88

Perimeter of rectangle = 38

perimeter of circle = 24 = 8

area of circle =   = 16

Step-by-step explanation:

Area of shaded region = Area of rectangle - area of semi circle

Rectangle:

length = 11 cm

Width = diameter of circle = 4 + 4 = 8 cm

Area 1 =  length * width

          = 11 * 8

          = 88 sq. cm

Circle:

radius  = r = 4 cm

Area of semicircle =  

Circumference of semicircle =

                                               = 3.14 * 4

                                               = 12.56 cm

Area of the shaded region = 88  - 25.12 = 62.88 = 63 square cm

Perimeter of shaded region = 11 + 8 + 11 + circumference of semicircle

                                                 = 11 + 8 + 11 + 12.56

                                                 = 42.56

                                                 = 43 cm
