What is the perimeter of quadrilateral ABCD?
alex41 [277]

Answer:

Perimeter of quadrilateral ABCD will be  104

Step-by-step explanation:

Given quadrilateral A'B'C'D' is a reflection of quadrilateral ABCD over the line m.

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

As both image are reflection of same scale we can add corresponding sides.

So, the perimeter of ABCD will be

AB+BC+CD+DA

And we have AB=A'B'\ and\ AD=A'D'

Now, perimeter of  ABCD will be 22+20+30+32

Perimeter of quadrilateral ABCD is 104
