I would appreciate if someone helps me with this question :)

When only separate discreet points are graphed it is called?

Uestion 1(multiple choice worth 5 points) (05.02)alex wants to paint one side of his skateboard ramp with glow-in-the-dark paint, but he needs to know how much area he is painting. calculate the area of the isosceles trapezoid. isosceles trapezoid with top base 12 feet, bottom base of 18 feet, and height of 6 feet. 72 ft2 84 ft2 90 ft2 108 ft2

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
