Carpets plus has five square carpet remnants. two of the remnants measure 8 feet on a side, and three of the remnants measure 10 feet on a side. which expression represents the total square footage of the five carpet remnants? (2 × 102) + (3 × 82) 82 + 103 5(8 + 10)2 (2 × 82) + (3 × 102)

I think you are missing a piece of information in your problem. What is the length of the carpet remnant? This would help us finalize the answer.

However, I think we can piece together an answer. I would select the final choice, because we are adding together a group of 3 and a group of 2. The group with 3 is the larger length, so it makes sense that this is also the largest area. I assumed that the width of each remnant is the same.
