Answer:
≈ 1468.59223 in squared
Step-by-step explanation:
1) A=2AB+(a+b+c)h
2) AB= square root of s(s﹣a)(s﹣b)(s﹣c)
3) s=a+b+c / 2
4) A=ah+bh+ch+1 / 2 square root of﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4
5) 18·22+18·22+18·22+1 / 2 x the square root of ﹣184+2·(18·18)2+2·(18·18)2﹣184+2·(18·18)2﹣184≈1468.59223
≈ 1468.59223 in squared
