I need to find the perimeter of a rectangle. P=2l + 2w. L=30

Step-by-step explanation:

P=2l + 2w is the formula for the perimeter of a rectangle of length l and width w.

If the length, l, is 30, then the perimeter is

P = 2 (30) + 2w, or

P = 60 + 2w

This is the general formula for the perimeter of lenth 30. Note that the width could have any value from 0 to infinity.

If you want a specific perimeter, you must specify the value of the width, w.
