Answer 2

Hello mate,

Here is your answer,

Radius of the semi-circle = 28/2 = 14 cm

Area of the 2 semi circles = 22/7 * 14 * 14 * 2 * 1/2

                                           = 616 cm

Therefore Perimeter of the figure = 616 + 7 + 7

                                                        = 630 cm
