We know that to find the perimeter of a rectangle, you use 2l%2B2w=p. We know 2 of the variables for the rectangle, so let's plug them in to get 2l%2B2%289%29=44. After simplifying, we get 2l%2B18=44. Now, we're trying to isolate the l to find it. So, we subtract the 18: 2l=26 and then divide by 2: l=13. There's your answer! The length of the rectangle is 13.
