Finding the Area of a Complex Shape

This video tutorial teaches how to find the area of complex shapes using subtraction. It begins with a review of rectangle properties and clarifies the difference between perimeter and area. The lesson then demonstrates calculating the area of a yard by subtracting the area of a doghouse. Finally, it covers finding the area of a yard excluding a swing set and a shed, reinforcing the concept of using subtraction to determine the area of complex shapes.

What is the main difference between perimeter and area?

• Perimeter measures the inside of a shape, while area measures the outside.

• Perimeter and area both measure the outside of a shape.

• Perimeter measures the outside of a shape, while area measures the inside.

• Perimeter and area both measure the inside of a shape.

How do you find the area of a complex shape with a doghouse attached?

• Add the area of the doghouse to the total area.

• Subtract the area of the doghouse from the total area.

• Multiply the area of the doghouse by the total area.

• Divide the area of the doghouse by the total area.

What is the area of a swing set with dimensions 2 yards by 3 yards?

• 5 square yards

• 8 square yards
