Answer:
the first shape if bigger by 7 so if you were to add 7 to the smaller on on each side you would get the same and equal length and you would not add a cm, m, ft ect because it does not have any information and if you automatically guess that its per say ft youll get the whole answer wrong because ft and cm are 2 way different things but different lengths
