Calculating Perimeter of Composite Shapes

The video tutorial explains how to find the perimeter of a composite shape consisting of a rectangle and a semicircle. It begins by describing the problem and the shape's components, then proceeds to calculate the perimeter by adding the lengths of the rectangle's sides and half the circumference of the semicircle. The tutorial concludes with the final calculation, determining the total length of the fence needed.

What is the main objective of the problem discussed in the video?

• To calculate the volume of a shape

• To find the perimeter of a composite shape

• To find the area of a composite shape

• To determine the diameter of a circle

What are the dimensions of the rectangle in the composite shape?

• 30 feet long and 15 feet wide

• 20 feet long and 10 feet wide

• 25 feet long and 12 feet wide

• 24 feet long and 14 feet wide

What is the shape of the end attached to the rectangle?

• A square

• A full circle

• A semicircle

• A triangle

Which side of the rectangle is parallel to the semicircle's diameter?

• The 14 feet side

• Neither side

• Both sides

• The 24 feet side

How do you determine the perimeter of the composite shape?

• By adding the areas of the rectangle and semicircle

• By adding the lengths of all sides and the semicircle's circumference

• By multiplying the lengths of the rectangle

• By subtracting the semicircle's area from the rectangle's area

What is the first step in calculating the perimeter?

• Identifying the dimensions of the rectangle

• Calculating the area of the rectangle

• 3.1

• 3.142

How is the semicircle's circumference calculated?

• By subtracting the diameter from pi

• By using the formula for the area of a circle

• By multiplying the diameter by pi and dividing by 2

• By adding the radius and pi

What is the calculated length of the semicircle's circumference?

• 10 feet

• 28 feet

• 14 feet

• 21.98 feet
