First add all of the givens   20 + 12 + 3.1 +3.1 +3.1  = 41.3 cm

now you need to find the length of the slanted side...using pythag theorem

height (one leg ) = 3.1 + 3.1 = 6.2 cm

Othe leg is  20 - (12+3.1) = 4.9

Find the slanted side length using Pythag Theor

L^2 = 6.2^2 + 4.9^2      L = ......... cm        <---------- add this to the 41.3 cm we found above for the total circ in cm
