Answer: 829 3/4 or 829 75/100
Step-by-step explanation:
The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
Surface area = 2(ab+bc+ac)
a=5.2 ft, b=2.4 ft, c=3.5ft
Surface area = 2(5.2 * 2.4 + 2.4 * 3.5 + 3.5 * 5.2) =
2(12.48 + 8.4 + 18.2) =
2 * 39.08 =
78.16 ≈ 78.2 ft² ← <span>to the nearest tenth</span>
