When I was working on an area question for school, I was solving a problem and the units in the answer were different than the one in the question. It was a question about two girls going on a picnic and you had to find the are of the picnic blankets and how much room they had to have their picnic. It had asked what the amount in feet was but the answer units next to the blank had said centimeters. I was not extremely confused but for further and new students working on it, I notified you so you could fix it. Thank you and have a great day:)
