Answer:

Step-by-step explanation:
we know that
If CD is parallel to XZ
then
Triangle XYZ is similar to Triangle YCD
therefore
The ratio of their corresponding sides are equal

we have
CX=5\ units, CY=25\ units, YD=20\ units,




substitute the values




Well if 49 is the area, and you get area by multiplying one side by another side, and its a square so the numbers are going to be the same, so you would be multiplying two of the same numbers. And two of the same numbers that equal 49 is 7.
