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)

ohh... I tried doing 4 x 9 would that be it or no?
jimthompson5910 (jim_thompson5910):
to this

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?

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

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