A tailor trims 4 feet from opposite edges of a square piece of cloth, and 5 feet from the other two edges. If 120 square feet of cloth remain, what was the length of a side of the original piece of cloth?
yes, you are right. Because it is "4 feet from opposite edges ". the most important word I had missed is " edges"!
