Convert 3 (1/2) into a mixed fraction first and then multiply it by 3:
3(1/2) * 3
(7/2) * 3
21/2
10 (1/2) = answer
The figure contains a triangle and a semicircle
The area of the figure is 49.12 square feet
<h3>How to determine the area</h3>
The dimension of the triangle is:
Base = 8 ft
Height = 6ft
So, the area is:
Area = 0.5 * Base * Height
This gives
Area = 0.5 * 8ft * 6ft
Evaluate
Area = 24 square feet
The radius of the semicircle is:
r = 4 ft.
So, the area is:
This gives:
Area = 0.5*3.14 * 4^2
Area = 25.12 square feet
Add the calculated areas.
Total = 24 square feet + 25.12 square feet
Total = 49.12 square feet
Hence, the area of the figure is 49.12 square feet

Answer:
The answer is E: I, II, and III
Step-by-step explanation:
The three major features of a well designed experiment are:
1. Replication: If an experiment cannot be replicated, then it is not a well-designed experiment. Replication is one of the major characteristics of a well designed experiment
2. Control: A well designed experiment must have a control. Control, in an experiment, can be referred to as the steps taken to curb the impact of extraneous variables
3. Randomization: Subjects are expected to be randomly assigned to different groups.
