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,
⇒
Therefore, the measure of the other side of a quadrilateral is cm.
