Question

Find the perimeter of the following shape

Answer 1

56. 50 for 2 semicircles Nd 6 for rectangle

Answer 2

take them as 2 half circle and 1 recangle

Perimeter of a rectangle = 2(l+b) 
                                             =2(16+3)
                                             =38 cm
Perimeter a circle = 2 π r
                                 =2 × 3.14 × 8  (diameter = 16
                                                            so radius =16/2)
                                 =50.24cm

area of that figure =area of rectangle+area of a circle
                                  =50.24cm + 38 cm
                                   =88.24 cm
