First, we need to find the distance between the points (9,-2) and (9,-11) to find the length of the vertical side of the quadrilateral.
Using the formula for distance between two points on a coordinate plane:
Distance = sqrt((x2-x1)^2 + (y2-y1)^2)
Distance = sqrt((9-9)^2 + (-11 -(-2))^2)
Distance = sqrt(0 + 9^2)
Distance = sqrt(0 + 81)
Distance = sqrt(81)
Distance = 9
Therefore, the length of the vertical side of the quadrilateral is 9 cm.
Given the coordinates (9,-2),(9,-11),(15,-4), and (15,-13), what is the length of the vertical side of the quadrilateral in cm
