Answer Happy

Andrea was given a problem about the area of a rectangle. Her teacher asked her to see what the area would be if the width of the rectangle is a 3-foot log and the length is made of two logs pushed together, a 4-foot log and a 3-foot log She couldn't see how to do the computation because she knew the area had to be in square feet. She got 3 times 4 to be 12 square feet and 3 times 3 to be 9 feet Andrea knew that they couldn't be the same units How would you help her? Choose the correct answer below @ A.
