Solution!!
The perimeter of parallelogram WXYZ is 50 millimeters.
Perimeter of the Parallelogram is equal to the Sum of allsides
WX + XY + YX + WZ
From the given figure,
WX = (2x + 9) mm
XY = (x - 5) mm
Since we know that opposite sides of Parallelogram are equal.
WX = YZ
WZ = XY
Plugging in the values,
Opening the brackets,
Combining the like terms,
Subtract 8 from both sides,
Divide both sides by 6,
Since, WZ = (x - 5)
Hence The value of WZ is 2 mm
