    Okay, so we know that the perimeter is 54 cm total. Looking at your drawing, add up all sides for perimeter and set it equal to 54cm. Now solve for the x"

    Rafael just told you exactly how to do it. Add up all the sides (x+x+6, or 2x+6) And set them equal to the total (54cm) So, your equation should look like 2x+6=54. Now solve.
