Length of side 1 $= 28$ Length of side 2 $= 56$ Length of side 3 $= 42$
Let $x$ be the shortest side. Length of side 1 $= x$ Length of side 2 $= 2x$ Length of side 3 $= 14 + x$ $x+2x+14+x=126$ $4x+14=126$ $4x=112$ $x=28$ Length of side 1 $= x=28$ Length of side 2 $= 2x=2(28)=56$ Length of side 3 $= 14 + x=14+28=42$
