In first figure
2.5+7.9+8.5=18.9
In second figure
19 1/2=19.5
40 2/3=41.3
Therefore (2x19.5)+(2x41.3)=121.6
In third figure
5+2+4+3+2+8=24
In forth figure
Cicumference of semi circle is 22
So 21+21+22=64
2.5+7.9+8.5=18.9
In second figure
19 1/2=19.5
40 2/3=41.3
Therefore (2x19.5)+(2x41.3)=121.6
In third figure
5+2+4+3+2+8=24
In forth figure
Cicumference of semi circle is 22
So 21+21+22=64
