Now way to do it in 1 command, as I know.
That's geometry: connect centres of the circles with a line, divide this lines proportionally to circles' radius - this point will be crossed by the tangent line to both circles.
R1=50
R2=20
L=L1+L2=224.88
R1/R2=L1/L2=50/20
We find
L1=160.63
L2=64.25
or draw 2 lines 50 and 20 and scale (50+20) to fit L=224.88.
