Question

Rectangle ABCDABCDA, B, C, D is graphed in the coordinate plane. The following are the vertices of the rectangle: A(2, 1)A(2,1)A, left parenthesis, 2, comma, 1, right parenthesis, B(5, 1)B(5,1)B, left parenthesis, 5, comma, 1, right parenthesis, C(5, 6)C(5,6)C, left parenthesis, 5, comma, 6, right parenthesis, and D(2, 6)D(2,6)D, left parenthesis, 2, comma, 6, right parenthesis. Given these coordinates, what is the length of side ABABA, B of this rectangle?

Answer 1

3

Explanation:

Answer 2

3

Explanation:

Points A and B lie on the horizontal line y = 1. The length of segment AB is then the difference of the x-coordinates of the points:

5 -2 = 3

The length of side AB is 3 units.
