line EA=1.8 < triangle ABCDE >triangle MIJKL
line LM=y
line AB=4.2 line MI=7
line CB=z line IJ=6
line DC=x line JK=5
line DE=3.2 line KL=W
So we are working with proportions and i need to find the scale factor of MIJKL to ABDCE, find the values of W,Y,X, and Z. Then i need to find the perimeter of the polygon. and then find the ratio of the perimeter of ABCDE to the perimeter of MIJKL. Please help me i need this grade and i have no idea how to do proportions!

1) Your statement "EA=1.8 < triangle ABCDE >triangle MIJKL" is confusing.
Let me take this as, The two pentagons, ABCDE and MIJKL are similar taken in order. And EA = 1.8 units.
2) If two geometrical figures are similar, then there corresponding sides are in proportion.
So, AB/MI = BC/IJ = CD/JK = DE/KL = EA/LM
==> 4.2/7 = Z/6 = X/5 = 3.2/W = 1.8/Y
Solving every one the above = 0.6, we have, Z = 3.6; X = 3; W = 16/3 and Y = 3
For perimeter find the sum of all sides.
