x,y,z
x%2By%2Bz

(5/2)x,(5/2)y,(5/2)z
%285%2F2%29%28x%2By%2Bz%29

%28x%2By%2Bz%29%2B%285%2F2%29%28x%2By%2Bz%29=133

Just say, perimeter of smaller triangle is p.
p%2B%285%2F2%29p=133
2p%2B5p=266
7p=266
p=38------smaller triangle perimeter.

38%285%2F2%29
19%2A5
highlight%2895%29-----------bigger triangle perimeter.
