Answer:
9.7m^2 if it needs to be rounded
Step-by-step explanation:
Theta = 210° r = 4.6/2 = 2.3 Area of circle = pi * r * r = 3.14 * 2.3 * 2.3 = 16.61 Area of sector = (theta / 360) * area of circle = (210/360) * 16.61 = 9.69

Parallel lines have the same slope. Hope this helps!
Use identity -
(a+b)² = a²+b²+2ab
(5+√3)² = 5²+(√3)² + 2(5)(√3)
= 25 + 3 + 10√3
= 28 + 10√3
= 2(14+ 5√3)
