Option B:
The perimeter of the figure is 16 + 2π.
Solution:
The clear image of the question is attached below.
Diameter of the semicircle = 7 – 3 = 4
Radius of the semicircle = 4 ÷ 2 = 2
Perimeter of the semicircle = 
In figure, one side of the semicircle is merged with rectangle, so remove two radius from the perimeter of the semicircle.
Perimeter of the semicircle =

= 2π units
Perimeter of the rectangle given = 3 + 7 + 3 + 3
= 16 units
Perimeter of the given figure = 2π + 16
= (16 + 2π) units
Hence the perimeter of the figure is 16 + 2π.
Option B is the correct answer.
Answer: 4 gallons will be needed.
Step-by-step explanation:
The bottom of the pool is rectangular in shape. The formula for determining the area of a rectangle is expressed as
Area = Length × width
Olympic-sized swimming pool of uniform depth measures 50 meters by 21 meters. The area of the bottom would be
Area = 50 × 21 = 1050 m²
The bottom of the pool is to be treated with a sealer, and one gallon of the sealer covers 300 square feet of surface. This means that the number of gallons of sealer required for the job would be
1050/300 = 3.5gallons Approximately 4 gallons to the nearest gallon
