Given is a composite figure where we have a semicircle and a triangle.
To find the area of the semicircle, we need diameter of the circle which is the distance between two given points (2,4) and (2,-3). So the diameter is 4-(-3) = 7 and radius would be 3.5 units.
Area of circle = π·r² = 3.14 × (3.5)² = 38.465
squared units.
So, area of semicircle = 38.465 ÷ 2 = 19.2325
squared units.
To find the area of the triangle, we need base and height of the triangle. The base is same as diameter = 7 and the height would be distance between given point (5,0) and (2,0), so height is 5-2 = 3.
Area of triangle 1/2 * 7 * 3 = 10.5
squared units.
Total area = Area of triangle + Area of semicircle = 10.5 + 19.2325 = 29.7325 squared units.
So, final answer is 29.7325 squared units.

Answer:
A. Ratio boys to girls ---> 19 : 26
B. Ratio of 5th grade to 6th grade ---> 21 : 24
C. Ratio of girls to total number of chorus students ---> 26 : 45
Step-by-step explanation:
A. the amount of boys is 9 + 10, the amount of girls is 12 + 26
B. the amount of 5th graders is 12 + 9, the amount of 6th graders is 14 + 10
C. the number of girls is 12 + 14, and the number of chorus students is 12+9+14+10
