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:
Option (C)
Step-by-step explanation:
If AD is the altitude to BC, both the segments AD and BC will be perpendicular to each other.
By the property of perpendicular lines,
where is the slope of the line AD and
is the slope of BC.
Now from the given property,
Therefore, slope of altitude BC =
