Answer:
Total area of the composite figure = 129.1 square units
Step-by-step explanation:
Area of the figure attached = Area of semicircle + Area of the rectangle
Since area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
where 'r' = radius of the circle
Area of the semicircle = [tex]\frac{1}{2}\pi (4)^{2}[/tex]
= 8π
= 25.1 square units
Area of the rectangle = Length × width
= 13 × 8
= 104 square units
Total area of the composite figure = 25.1 + 104
= 129.1 square units
