The total lenght is 4 times the width. Width = 13in. 13 * 4 = 52

OpenStudy (sleepyjess):
yes, since the previous responder gave that to you, but do you know how to get to that?

i did L*4 since the length was 13 13*4

OpenStudy (sleepyjess):
yes! good job :) now, since P = length + length + width + width, we can just substitute in the values of length and width
