In the adjoining figure , `angleBCD=angleADB` (each `90^(@)`) . angle BC= 3 cm and length of side opposite `angleC` in `DeltaBCD` is 5 cm , then find the squre root of length of side opposite to `angleD` in `DeltaADB`.

Explanation

To solve the problem step by step, we will follow the given information and apply the Pythagorean theorem where necessary.

### Step 1: Understand the problem
We have two triangles, ΔBCD and ΔADB, with the following information:
- Angle BCD = Angle ADB = 90 degrees
- BC = 3 cm
- The length of the side opposite angle C (BD) in ΔBCD = 5 cm
- We need to find the square root of the length of the side opposite angle D (AB) in ΔADB.
