First, distribute the 3 to the parentheses.
2x + 16 = 3x - 27
Add 27 to the left.
2x + 43 = 3x
Subtract 2x to the right.
43 = x

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 $104$
