A gardening box has a perimeter of 27 1/2 feet. if the length is 9 feet, what is the area?

To figure out the width is easy all you do is subtract the length twice, because of there being 2 sides that have the same length, and then divide whatever is left. So its 27.5-18=9.5. 9.5/2=4.75. 4.5 is your width. and now area. area=length times width, so a = 9 times 4,75, which is 42.75.
