Based on the definition of the diagonal of a rectangle, the length of DE is: D. 15.
Diagonals of a Rectangle
- The diagonals of a rectangle are congruent, meaning they have equal length measure.
- The diagonals also bisect each other, dividing each into equal segments.
Thus:
AC = 30 units.
AC = DB
DB = 30 units
Therefore:
DE = 1/2(DB)
DE = 1/2(30)
DE = 15 units
Therefore, based on the definition of the diagonal of a rectangle, the length of DE is: D. 15.
