Final answer:
The length of diagonal BD in rectangle ABCD is -6.
Step-by-step explanation:
In this question, we are given that rectangle ABCD with one of its diagonal AE = -6. We need to find the length of the other diagonal, BD.
To find the length of BD, we can use the fact that the diagonals of a rectangle are equal in length. So to find the length of BD, we can use the length of AE. Since AE = -6, BD will also be -6.
Therefore, the length of BD is -6.
