Given the coordinates (3,-2) (11.-2) (3,-4) and (11,-4) what is the length of the base of a quadrilateral in centimeters

To find the length of the base of the quadrilateral, we need to find the distance between the points (3,-2) and (11,-2) or the distance between the points (3,-4) and (11,-4).

First, let's find the distance between (3,-2) and (11,-2):

Distance = √((11-3)^2 + (-2-(-2))^2)
Distance = √(8^2 + 0^2)
Distance = √64
Distance = 8

So, the length of the base of the quadrilateral is 8 cm.
