 Oct 24, 2010 Rating Area Formula Problem by: Karin There are two formulas that you must know in order to complete this problem. 1. The formula for finding area of a rectangle is A = l x w. Area = length times width. 2. The problem gives you dimensions in feet, but asks for the answer to be in yards. You must know that 3 feet = 1 yard. So, first we must convert feet to yards. Since 3 feet = 1 yard, if you divide the number of feet by 3, you will know how many yards. The length is 15 feet. 15 /3 = 5 yards. Therefore, the length is 5 yards long. The width is equal to y feet. We must still convert this to yards. Therefore, y/3 = the width. You can also write this as 1/3y. Now we have: length = 5yds width = 1/3y yds. A = l x w A = 5 x 1/3y A = 5/3y A = 5/3y is the area of the room. Remember to first convert the dimensions to yards and then apply the area formula. I hope this helps, Karin
