Answer:
answer is 24.56cm
perimeter of half/semi circle = [tex]\pi[/tex] r + 2r
one semi circle semi circles perimeter: [tex]\pi[/tex]*2+2*2 =10.283cm,
for two semi circles= 2*10.283 =20.566cm
without the line below for two semi circle: 20.566-4-4=12.566 cm
both da side of rectangle is 6cm+6cm=12cm
now add the 12.566+12=24.56cm
