The Area of the figure ≈ 19 units²
What is the Area of a Semicircle and a Triangle?
Area of a semicircle = 1/2(πr²), where r is the radius.
Area of a triangle = 1/2(b)(h), where b is the base and h is the height of the triangle.
The figure can be decomposed into a semicircle and a triangle.
Area of the figure = 1/2(πr²) + 1/2(b)(h)
r = 1/2(7) = 3.5 units
π = 3.14
b = 7 units
h = 3 units
Substitute
Area of the figure = 1/2(3.14)(3.5²) + 1/2(7)(3)
Area of the figure ≈ 19 units²
