|dw:1409800589002:dw| You have P = 32. What else is p equal to?

OpenStudy (anonymous):

Idk, I'm sorry. I'm really bad at this

OpenStudy (bibby):

The perimeter is just all the sides added up, right?

OpenStudy (anonymous):

Yeah , would it be 8?

OpenStudy (bibby):

how'd you get that? Add up the sides L+L+W+W=32

OpenStudy (bibby):

hmm?

OpenStudy (anonymous):

so the length would be 10 and thw width would be 6?

OpenStudy (bibby):

oops 5x+5x+3x+3x=32 16x=32 x=2 5:3 = 10:6 you're right sorry
