The answer is P = 2(l+w) units.
This is because when you let the perimeter of the rectangle be P, the length of the rectangle be l and the width of the rectangle be w.
The information above can be expressed as the following equation,
P = 2l + 2w
You can then factorise out the common factor, 2.
P = 2(l+w)
Thus, the answer is P = 2(l+w) units.
