please help me with sample coding y1 Zgy and The area of a t

please help me with sample coding!!!!

.y1), (Zgy), and The area of a triangle whose three vertices are points( (x3, ys) (see Figure 6.6) can be found from the equation 6.8 (6.12) where || is the determinant operation. The area returned will be positive if the points are taken in counterclockwise order and negative if the points are taken in clockwise order. This determinant can be evaluated by hand to produce the following equation 112 Write a function area2d that calculates the area of a triangle, given the three bounding points (xi,yi), (x2./2), and (xs, ys) using Equation (6.13). Then test your function by calculating the area of a triangle bounded by the points (0,0), (10,0), and (15,5).

Solution

x1=input(\'x1=\');

y1=input(\'y1=\');

x2=input(\'x2=\');

y2=input(\'y2=\');

x3=input(\'x3=\');

y3=input(\'y3=\');

v1=[x1 y1];

v2=[x2 y2];

v3=[x3 y3];

a=sqrt((x1-x2)^2+(y1-y2)^2);

b=sqrt((x2-x3)^2+(y2-y3)^2);

c=sqrt((x3-x1)^2+(y3-y1)^2);

if a > 0 & b > 0 & c > 0 & (a + b > c) & (a + c > b) & (b + c > a)

plot([x1 x2 x3 x1],[y1 y2 y3 y1])

else
