What is the perimeter of quadrilateral A' B' C' D'? Explanation:
Quadrilateral A B C D is translated 2 units to the left and 5 units down to create quadrilateral A' B' C' D'.

14.2 Units

Step-by-step explanation:

The second shape is given to confuse you and is not actually necessary.

To work out the perimeter of an irregular shape you simply add up the lengths of each side. The shape you have here is an irregular quadrilateral as it has four corners and no recognisable/coarrale organisation.

1.4units + 2.2units + 4.5units +6.1units = 14.2 units.

I hope this helps :)
