Answer:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=10·4+6·4+8·4+1
2·﹣104+2·(10·6)2+2·(10·8)2﹣64+2·(6·8)2﹣84=144

You'd have to find the average! (:
So add 14 and 16 to get 30, so your answer would be x/30
Since there are 14 boys, that would be x. 14/30 Simplify that to get 7/15!
