Question

What is the perimeter of quadrilateral ABCD?

18+ 2 units
18+ V6 units
O 18 + /26 units
18 + 50 units

Answer 1

18 + √26

Explanation:

You will have to use distance formula
`d = \sqrt{(x2-x1)^(2) + (y2-y1)^(2)}` between all 4 points to solve this. Once you have found the lengths between the points, you can add them all together. When you add them all together you should get 18 + √26 as your answer.
