6 + 4 + 4 = 14 cm
2 * pi * r = 
2 * 3.14 * 3 = 18.84 / 2 = 9.42
14 + 9.42 = 23.42
Perimeter of figure = 3 sides of rectangle + perimeter of semi-circle.3 sides of rectangle = 15 + 12 + 15 = 42 Perimeter of semi-circle = πr = 3.14 * 6 = 18.84In short, Your Answer would be: 42 + 18.84 = 60.84 m.
Hope this helps
