Thats a 7 o.o

OpenStudy (rogue):

7 is the height.

OpenStudy (mertsj):

So add all the sides to find the perimeter.

OpenStudy (rogue):

The opposite sides of a parallelogram are equal.

OpenStudy (rogue):

THe 7 is useless info., unless its for another part of the quesiton.

OpenStudy (anonymous):

Thanks lol i kept counting the 7

OpenStudy (rogue):

The 7 is used for area. A = b * h

OpenStudy (anonymous):

So in another problem I wouldn't count the dotted lines height o.o ?

OpenStudy (rogue):

If it was asking for perimeter, no. If area, yes.
