Find the length of a diagonal of a rectangle abcd with vertices a (-3, 1) b (-1, 3) c(3, -1) and d (1,-3)

The length of the diagonal may be determined by using the points A and C or B and D. Choosing A and C, the length of the diagonal is,
                             d = sqrt ((x₂ - x₁)² + (y₂ - y₁)²)
Substituting the known variables,
                             d = sqrt (3 - -3)² + (-1 - 1)²)
                                   d = sqrt 40
