Answer:
A≈114.12
Explanation:
A=2AB+(a+b+c)h AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c/2
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=9·5+6·5+4·5+1
2·﹣94+2·(9·6)2+2·(9·4)2﹣64+2·(6·4)2﹣44≈114.12459
here is the full explanation , I took a blackboard pavcs math quiz
The answer is 168!
6*4=24 (There are two triangles so you don't have to divide by 2, 24 is simply the answer to both), 6*9=54, 5*9*2=90, 90+54+24=168! I hope this helps! Have a great rest of your day!
