Answer:
<h2>
8 units²</h2>
Step-by-step explanation:
Let side of the square = a
The , Area of square = a²
Now, Midpoint of Diagonal DB is E
And DE = 2 units
So, DB = 2 DE = 2 × 2 = 4 units
Now, using Pythagoras theorem in ∆ BCD
DB² = DC² + BC²
plug the values

Collect like terms

Evaluate the power

Swipe the side of the equation

Divide both sides of the equation by 2

Calculate

Therefore, The area of the square is 8 sq.units.
Hope this helps..
