Perimeter and Area of Composite Figures

The video tutorial explains composite figures, focusing on calculating their perimeter and area. It covers different methods for these calculations, including adding sides for perimeter and using subtraction or addition of areas for area. Two example problems are solved, demonstrating these methods and offering alternative approaches for easier understanding.

What is a composite figure?

• A figure that is always a rectangle

• A figure made of multiple simple shapes

• A figure made of only circles

• A figure with no sides

How do you find the perimeter of a composite figure?

• Multiply all the sides

• Add all the sides

• Subtract the sides

• Divide the sides by two

What does calculating the area of a composite figure involve?

• Dividing the area by the number of sides

• Multiplying the perimeter by two

• Subtracting or adding areas of smaller shapes

• Only adding areas of circles

In the example, what is the perimeter of the composite figure?

• 78 meters

• 52 meters

• 36 meters

• 44 meters

How is the area of the composite figure calculated in the example?

• By multiplying the perimeter by the height

• By subtracting the area of a smaller shape from a larger one

• By adding the areas of all shapes

• By dividing the total area by the number of shapes

What units are used for measuring perimeter?

• Meters or centimeters

• Liters

• Cubic meters

• Square meters

What is the perimeter of the second composite figure example?

• 52 meters

• 44 meters

• 36 meters

• 78 meters

What is an alternative method for finding the perimeter?

• Ignoring the smaller shapes

• Guessing the perimeter

• Rearranging segments to form a rectangle

• Using a calculator

How is the area calculated in the second example?

• By dividing the total area by the number of rectangles

• By subtracting the area of a circle

• By adding the areas of two rectangles

• By multiplying the perimeter by the width

What is the total area of the composite figure in the second example?

• 36 meters squared

• 52 meters squared

• 44 meters squared

• 78 meters squared
