Answer:
Step-by-step explanation:
The formula for determining the area of a triangle is expressed as
Area = 1/2 × base × height
Base = 3 units
Height = 6 units
Area = 1/2 × 3 × 6 = 9 units²
The formula for determining the area of a semicircle is expressed as
Area = 1/2 × π × r²
Where
π is a constant whose value is 3.14
r represents the radius of the semicircle.
Diameter = 3 units
Radius = diameter/2 = 3/2
r = 1.5 units
Area = 1/2 × 3.14 × 1.5² = 3.5units²
Area of the figure is
9 + 3.5 = 12.5 units²
