First subtract 100v² from both sides to get:
C²L²=100c²-100v²
Then divide both sides by C²:
L²=(100c²-100v²)/C²
Then take the square root of both sides:
L=+ or - the square root of (100c²-100v²)/C²

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
