there's a cool trick you can use...since perimeter means sum of all sides do this:

2x + 3x + 4x = 72

find x

parthkohli · Answer

x is a constant by which they are multiplied.

lgbasallote · Answer

once you've done that...multiply x by 2 to get the first side


multiply x by 3 to get the second side

multiply x by 4 to get the third side

parthkohli · Answer

parthkohli · Answer

Oh you mean after we get x.

parthkohli · Answer
