Question

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of

the rectangle: A(-1,-6), B(-1,7), C(1,7), and D(1, -6).
Given these coordinates, what is the length of side AB of this rectangle?
units

Answer 1

Answer: 13 units

Explanation:

AB=

|A-B|=

|(-1, -6)-(-1, 7)|=

|(-1-(-1), -6-7)|=

|(-1+1, -13)|=

|(0, -13)|=

|-13|=13 units
