Answer:
418.2477796 m
Step-by-step explanation:
You divide it in to a rectangle and 2 half circles (which will make a whole circle if added together) and solve them.
P= 2( L + W) - - > 2 ( 102 + 60)= 324
- Circle (has a circumference not a perimeter)
Cf= 2лr^2 - - - > 2л(30)^2=30л
324 + 30л = 418.2477796 m
