Question 610633
We know that to find the perimeter of a rectangle, you use {{{2l+2w=p}}}. We know 2 of the variables for the rectangle, so let's plug them in to get {{{2l+2(9)=44}}}. After simplifying, we get {{{2l+18=44}}}. Now, we're trying to isolate the <i>l</i> 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.
