What is the length and width of the rectangle?
Three rectangles of different sizes make up a larger rectangle. The larger rectangle's length is labeled length. The larger rectangle's width is labeled width. The smaller rectangle on the left has fifteen k to the fourth power inside it. The smaller rectangle in the middle has thirty five k cubed inside it. The smaller rectangle on the right has twenty k squared inside it.
