Work Step by Step

Let the shortest side of the triangle be $x$ Given, Length of one side is twice the length of the shortest side $y=2x$ Equation $(1)$ Length of the third side is $14$ more than the length of the shortest side. $z = 14 +x$ Equation $(2)$ Perimeter of the triangle is $126$ units $x+y+z=126$ $x+2x+14+x=126$ $4x=126-14$ $4x=112$ $x=28$ units $y=2x$ $y=2(28)$ $y=56$ units $z = 14 +x$ $z = 14 +28$ $z = 42$ units
