Answer:
[tex]BD = 12\ cm[/tex]
Step-by-step explanation:
Given
Shape: Rectangle
Diagonals: AC and BD
[tex]AC = 12\ cm[/tex]
Required
Determine BD
From the question, we understand that the shape is a rectangle and its diagonals are AC and BD
Every rectangle has 2 diagonals, both of which are equal.
This implies that:
[tex]BD = AC[/tex]
Recall that:
[tex]AC = 12\ cm[/tex]
Hence,
[tex]BD = 12\ cm[/tex]
