I dont even know what you are talking bout just saying
The measure of the other side of a quadrilateral is
cm.
In the given quadrilateral one side is unknown we need to find the unknown side.
By dividing the given quadrilateral into a rectangle and a triangle we can find the other side.
<h3>What is Pythagoras theorem?</h3>
The Pythagoras theorem states that if a triangle is right-angled, then the square of the hypotenuse is equal to the sum of the squares of the other two sides. That is,
.
Now, ![x^{2} =9^{2}+6^{2}=81+36=17](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D9%5E%7B2%7D%2B6%5E%7B2%7D%3D81%2B36%3D17)
⇒![x=\sqrt{13 \times 9} =3\sqrt{13}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B13%20%5Ctimes%209%7D%20%3D3%5Csqrt%7B13%7D)
Therefore, the measure of the other side of a quadrilateral is
cm.
