-5x-16=8
-5x=24



above is how to correctly solve the equation
The error is in step 3.
Step 3 as written: 
This is incorrect because you are removing the 5 from the -5x so it wouldn't be in the numerator.
Hope this helps
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)
