(Geometry: polygon subareas) A convex 4-vertex polygon is divided into four triangles, as shown in Figure 8.8. V2 (x2, y2) V1 (x1, y1) V3 (x3, y3) V4 (x4, y4) A 4-vertex polygon is defined by four vertices. Write a program that prompts the user to enter the coordinates of the four ver- tices and displays the areas of the four triangles in increasing order. Here is a sample run:

*Please help in javascript* Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */}}

(Area of a convex polygon) A polygon is convex if it contains any line segment that connects two points of the polygon. Write a program that prompts the user to enter the number of points in a convex polygon, then enter the points clockwise, and display the area of the polygon. Sample Run Enter the number of points: 7 Enter the coordinates of the points: -12 0 -8.5 10 0 11.4 5.5 7.8 6 -5.5 0 -7 -3.5 -5.5 The total area is 244.575
