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

${4}^{2} = {a}^{2} + {a}^{2}$

Collect like terms

${4}^{2} = 2 {a}^{2}$

Evaluate the power

$16 = 2 {a}^{2}$

Swipe the side of the equation

$2 {a}^{2} = 16$

Divide both sides of the equation by 2

$\frac{2 {a}^{2} }{ 2 } = \frac{16}{2}$

Calculate

${a}^{2} = 8$

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

Hope this helps..

Best regards!!

The general form of the equation of a circle is Ax2 By2 Cx Dy E = 0, where A = B 0. If the circle has a radius of 3 units and th

Tems11 [23]

The other form of circle equation is (x-a)2 + (y-b)2 = r2. a and b is the coordinate of the center and r is radius. So the equation is x2+(y-4)2=9. Change it to the general form is x2+y2-8y+7=0. So A=1, B=1, C=0, D=-8 and E=7.
