Knowing that the object is a rectangle, and that the base is 2x the height, you could say that h=height and b=base (and the base is the same as width since the object is a rectangle) then a possible equation you could construct is 2(h+2b)
Step-by-step explanation:
For example, using this equation with numbers may look like the following:
2(h+2b)
2(21+2*21)
2(21+42)
2(61)
=122
Hopefully I was able to help you :) I would love to hear some feedback if possible and if you were able to find a simpler way.
