if a triangle with square attached have areas of 6 square units for the smallest square and 10 square units for the largest square, what is the missing area? what are the side lengths for the triangle?

This question does not make much sense to me. Do you think you could rephrase this and post again. I'll try to help. As of now you said there is a triangle with a square attached (singular) yet you're giving me the areas of 2 different squares. I'm a tad bit confused.
