Question
Given the coordinates (3,−2) , (11,−2) , (3,−4) , and (11,−4) , what is the length of the base of the quadrilateral, in cm?

Answer 1

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

Using the distance formula:
Distance = √((11-3)^2 + (-2-(-2))^2)
Distance = √(8^2 + 0^2)
Distance = √(64)
Distance = 8 cm

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