Hint :by definition a rhombus has all 4 sides equal to one another (it's like a square, but the angles don't have to be all equal to 90 degrees)

jimthompson5910 (jim_thompson5910):

|dw:1358983018387:dw|

jimthompson5910 (jim_thompson5910):

so we go from this |dw:1358983045391:dw|

OpenStudy (anonymous):

ohh... I tried doing 4 x 9 would that be it or no?

jimthompson5910 (jim_thompson5910):

to this |dw:1358983058137:dw| because we know that any rhombus has all four sides equal

jimthompson5910 (jim_thompson5910):

you can either add them up, or use the formula you wrote out since s+s+s+s is the same as 4s

OpenStudy (anonymous):

Ohh okay so you basically add up all the 4's?

OpenStudy (anonymous):

I mean add up all the 9's?

jimthompson5910 (jim_thompson5910):

yep

jimthompson5910 (jim_thompson5910):

s+s+s+s 9+9+9+9 ... since s = 9 in this case ???

OpenStudy (anonymous):

awesome! Okay so i added 9 + 9 + 9 + 9 and god 36!

jimthompson5910 (jim_thompson5910):

yep, 9+9+9+9 = 36

jimthompson5910 (jim_thompson5910):

shortcut is to use the formula you wrote down P = 4s P = 4*9 P = 36
