ANSWER:

K = 4

Step-by-step EXPLANATION:

a1 = 2, B1 = -4, c1 = -7

a2= -2, b2 =2,c2=k

area of triangle = 1/2 a1(b2- c2)+ b1(c2-c1)+

c1(a2-b2)

0 = 1/2(2(2-k)+-4(k+2)+(-7)(-2-2)

0 = 1/2(4-2k-4k-8+28)

0 = 1/2(-6k+24) -----(i)

(i)/2----->

= 3k+12

3k = 12

k = 12/3

k = 4

hope it HELPFUL for you.
