Answer 1

So we have a rectangle and a half circle...

First, to find the half circle's perimeter we use C = (3.14)d

C = (3.14)(6) = 18.84

However, in this case, we have a half circle so we will divide that answer in half to get 9.42 as the half circle's perimeter...

So we just add 6 + 3 + 3 + 9.42 and you will have an answer of 21.42 mm or rounded to 21.4 mm
