Vaughn pang sketched trapezoid ruiz on a coordinate plane. ruiz has vertices located at r 1,4), u(-2,0), (7,0), and z(3,4). which of the following is the perimeter of ruiz?

To determine the perimeter of the trapezoid, we just have to determine the distance between the pair of points which can be calculated through the equation,
                                  d = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting,
     (1,4) and (-2,0)        d = √(1 - -2)² + (4 - 0)² = 5
     (-2,0) and (7,0)        d= √(-2 - 7)² + (0 - 0)² = 9
     (7,0) and (3,4)         d = √(7 - 3)² + (0 - 4)² = 5.66
    (3,4) and (1,4)          d = √(3 - 1)² + (0 - 0)² = 2

The perimeter is the sum of the distances. Thus, the answer is 21.66.
