Mr. Moreno said, “I think you are ready for a more challenging problem. Maybe you can help me out with this one. I am going to carpet my front hall. It measures 8.5 feet by 7.5 feet.”

Mr. Moreno challenged his students to find out how many square feet of carpet he needs to buy.

“I can estimate the area for you, Mr. Moreno,” said Jacob. “8.5 feet is about 9 feet, and 7.5 feet is about 8 feet. 9 feet  8 feet  72 square feet of carpet.”
