Given xy = yz
Therefore the two triangles in the question have the same base. Also they have the same height which is the perpendicular dropped from point w to the line xz
Hence they have the same area

Quantity A	Quantity B
The area of XWY	The area of YWZ

A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.

Look at the attached figure..
Draw a perpendicular from W to line XZ meeting at A
The area of XWY = \(\frac{1}{2}*XY*AW\)
The area of YWZ = \(\frac{1}{2}*ZY*AW\)... now ZY=AW...
Therefore, the area of YWZ = \(\frac{1}{2}*ZY*AW\)=\(\frac{1}{2}*XY*AW\)=area of XWY
