Answer:
Perimeter of quadrilateral
will be ![104](https://tex.z-dn.net/?f=104)
Step-by-step explanation:
Given quadrilateral
is a reflection of quadrilateral
over the line
.
So, all the corresponding sides of both the quadrilateral should be equal.
Also, we can see from the diagram that ![A'D'=32,\ A'B'=22,\ BC=20,\ and\ CD=30](https://tex.z-dn.net/?f=A%27D%27%3D32%2C%5C%20A%27B%27%3D22%2C%5C%20BC%3D20%2C%5C%20and%5C%20CD%3D30)
As both image are reflection of same scale we can add corresponding sides.
So, the perimeter of
will be
![AB+BC+CD+DA](https://tex.z-dn.net/?f=AB%2BBC%2BCD%2BDA)
And we have ![AB=A'B'\ and\ AD=A'D'](https://tex.z-dn.net/?f=AB%3DA%27B%27%5C%20and%5C%20AD%3DA%27D%27)
Now, perimeter of
will be ![22+20+30+32](https://tex.z-dn.net/?f=22%2B20%2B30%2B32)
Perimeter of quadrilateral
is ![104](https://tex.z-dn.net/?f=104)

Answer:
Step-by-step explanation:
it means that
125-30 < u < 125+30 so
95 < u < 155
it gives ![]95,155[](https://tex.z-dn.net/?f=%5D95%2C155%5B)
