Question

Quadrilateral A B C D is reflected across line m to create quadrilateral A' B'C'D'.

Answer 1

The perimeter of ABCD is 104 units

How to find the perimeter

Perimeter is solved by adding the sides. It is important to know that reflection preserves the dimension of the object. Hence the size remains congruent before and after reflection.

That is to say

AB = A'B'

BC = B"C'

CD = C'D'

DA = D'A'

Perimeter = 22 + 20 + 30 + 32

Perimeter = 104 units

Answer 2

`\begin{gathered} \text{Perimeter = A+B+C+D} \\ \text{Perimeter = }20+30+32+22 \\ \text{Perimeter= 104} \\ \text{The perimeter is }104 \end{gathered}`
