A = 9 b = -5

45 = 4a + 2b +c

45 = 4(9) + 2(-5) + c

Answer:

161.1 m² (1 dp)

Step-by-step explanation:

Area of a triangle = 1/2 x base x height

⇒ area = 1/2 x 12 x (20 - 12) = 48 m²

Area of a quarter circle = $\dfrac14\pi r^2$

⇒ area = 1/4 x $\pi$ x 12² = 113.1 m² (1 dp)

Total area = 48 + 113.1 = 161.1 m² (1 dp)
