68+33+34+10= 145 m
then your cm's
700+400= 11 m
145+11= 156 m
then we need to add half of the total circumference of that circle which we can find with the provided 17 m radius
Now C =2(3.14)^r
in this case C = 106.81 m
106.81/2= 53.405 m
this can then be added to our previous sum of 156 m
156 + 53.405 = 209.405 m as the total perimeter !
