Answer:

  1. 6 units
  2. 13 units
  3. 5 units

Step-by-step explanation:

You want the lengths of the unknown sides in the given trapezoid figure, knowing that the perimeter is 18 units.

1.

The side AB is a vertical line segment, so its length can be found by finding the difference of y-coordinates of its end points.

  AB = (2) -(-4) = 2+4 = 6

The length of AB is 6 units.

2.

The sum of the lengths of vertical and horizontal segments is ...

  AB +BC +CD = 6 +4 +3 = 13

The total distance from A to D along vertical and horizontal segments is 13 units.

3.

The perimeter is the sum of the lengths of all sides.

  perimeter = AB +BC +CD +AD

  18 = 13 + AD . . . . . . substitute known values

  5 = AD . . . . . . . . . subtract 13

The length of segment AD is 5 units.

Additional comment

Finding the length of a vertical or horizontal line is no different than finding the distance between two points on a number line.
