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 = 
⇒ area = 1/4 x
x 12² = 113.1 m² (1 dp)
Total area = 48 + 113.1 = 161.1 m² (1 dp)
Answer:
One solution
Step-by-step explanation:
y = 2x – 5. –8x – 4y = –20. one solution: (–2.5, 0)
