If v is cut in half, then w is multiplied by (1/(1/2))^2 = 4.
When v=3, w=12.
Watch to find the midpoint:

92 = 11 + 12 + 13 + 2(a) + 4(3a)
92 = 36 + 2a + 12a
92 = 36 + 14a
-36 -36
56 = 14a
56/14 = 14a/14
a = 4
Answer:
23.6
Step-by-step explanation:
A=1/2abSinC
A=1/2*6*8*Sin80
= 24 * Sin 80
=23.635
