Mr. Stewart's lawn has a length of 11 feet and a width of 8 feet. He has procrastinated and not mowed his lawn for weeks. Unfortunately, he only has the time and energy to mow half of his lawn today. How many feet of lawn will he mow?
Discuss with your team some strategies on how to go about figuring out this problem.
44 sq feet of lawn.
