Answer:
I believe the answer is A - graph W
Step-by-step explanation:
The square has 4 sides of the same measure.
If square SQUA has a side measuring 25 mm, it means side QU measures the same.
Also, if quadrilateral AQER is a square two, then its diagonals bisect each other, then QU is equal to UR.
Thus, QR measures:
The answer is 50 mm
