Answer:
Explanation:
assuming it is a rectangle, there is no information on the shape of the quadrilateral, add all sides.
7 + 8 + 7 + 8 = 30 units
30
What you need to do is add all the sides when you want to find perimeter so for this one you would want to do 8+8+7+7 and that should give you 30. I hope I could help!!
