Answer:
8 units²
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
[tex] {4}^{2} = {a}^{2} + {a}^{2} [/tex]
Collect like terms
[tex] {4}^{2} = 2 {a}^{2} [/tex]
Evaluate the power
[tex]16 = 2 {a}^{2} [/tex]
Swipe the side of the equation
[tex]2 {a}^{2} = 16[/tex]
Divide both sides of the equation by 2
[tex] \frac{2 {a}^{2} }{ 2 } = \frac{16}{2} [/tex]
Calculate
[tex] {a}^{2} = 8[/tex]
Therefore, The area of the square is 8 sq.units.
Hope this helps..
Best regards!!
