The legs of the triangle are x and 2x+4 cm.
(x)(2x+4) = 2 * 120
2x^2 + 4x - 240 = 0
x^2 + 2x - 120 = 0
(x+12)(x - 10) = 0
The sides are 10 cm and 24 cm, so the perimeter is 10+24+26 = cm.

Is the "other side" a leg, too ?
BY THE WAY
For right triangle, the standard naming of its sides forming the right angle is one short English word of three letters,
and this word is "leg".
