Answer:
48 + 18√13 cm²
Step-by-step explanation:
HC = BC/2 = 4m/2 = 2 m
AC = √AH² + HC² = √9 + 4 = √13
A = 2×A(ABC) + 2×A(ACFD) + A(BCFE)
= 2×AH×BC/2 + 2×AC×CF + BC×CF
= 2×3×4/2 + 2×√13×9 + 4×9
=12 + 18√13 + 36
= 48 + 18√13 cm²

Answer: No. The answer to this system is y=−85 and y=5, and if you plot that and (3,4) on a graph (I did it on desmos), you will see that it is one square down from the system, meaning it is not a solution to the system. Hope this helps and have a great day!
