ABCD is a rectangle. Its diagonals are AC and BD. If AC = 12cm, then BD = cm

Step-by-step explanation:

Given

Shape: Rectangle

Diagonals: AC and BD

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:

Recall that:

Hence,
