now The length of a rectangle is 5 times the width. What is the perimeter of the rectangle if the width is 12 inches?

OpenStudy (matthew120):

A. 240 inches B. 72 inches C. 120 inches D. 144 inches

OpenStudy (anonymous):

I think it's 144

OpenStudy (matthew120):

i need 100 % plz not to be mean

OpenStudy (trwatkins1):

i thought it would be 60 but thats not a answer

OpenStudy (anonymous):

ok so you know the length is 5 times it's width so u multiply 12 times 5

OpenStudy (anonymous):

60 +60 is 120. And 12+12=24 add them together = 144

OpenStudy (candyme):

Ok, so l=5w and w=12 So you want to know the perimeter, which is 2l+2w 2(12)+2(5(12)) 24+2(60) 24+120 144

OpenStudy (candyme):

@April1010 is correct
