Answer:
<em>"Use the distance formula to find the length of each side, and then add the lengths".</em>
Step-by-step explanation:
By definition the perimeter of a quadrilateral is the sum of the length of its sides.
Therefore the first thing we should find is the length of the sides of the quadrilateral
If we have the vertices A, B, C and D of the quadrilateral then the distance between two of its vertices is the length of one of its sides.
For example, the distance between vertex A and vertex B is the length of the AB side. Then, using the formula of the distance between two points, we find the length of its sides and add them together.
Then the correct answer is: <em>"Use the distance formula to find the length of each side, and then add the lengths".</em>
