Understanding Perimeter and Unit Conversion

The video tutorial addresses a perimeter problem where Wally needs to calculate the amount of fencing required for his backyard. The tutorial explains how to convert measurements from yards to feet and then calculates the total fencing needed by summing up the lengths of different sections. The final solution determines that Wally should purchase 81 feet of fencing.

What is the purpose of Wally's fence?

• To improve the house's appearance

• To mark his property boundary

• To create a safe play area for his children

• To keep animals out

How long is the back wall of Wally's house in yards?

• 10 yards

• 15 yards

• 25 yards

• 20 yards

What is the first step in solving Wally's fencing problem?

• Visit the store to buy materials

• Determine the purpose of the fence

• Add the lengths of all sides

• Convert all measurements to the same unit

What is the conversion factor from yards to feet?

• 1 yard = 3 feet

• 1 yard = 2 feet

• 1 yard = 4 feet

• 1 yard = 5 feet

How many feet is the back wall of Wally's house after conversion?

• 30 feet

• 45 feet

• 35 feet

• 40 feet

Why is it important to convert the back wall measurement to feet?

• To reduce the cost of fencing

• To simplify the diagram

• To ensure all measurements are in the same unit

• To make it easier to calculate the area

What is the total length of the fence on the side opposite to the 10 feet side?

• 5 feet

• 10 feet

• 15 feet

• 20 feet

What is the total length of the fence along the back and one side?

• 83 feet

• 73 feet

• 63 feet

• 53 feet

What is the total length of fencing Wally needs to purchase?

• 85 feet

• 75 feet

• 80 feet

• 81 feet

Which of the following is NOT a step in calculating the total fencing needed?

• Ensuring all measurements are in the same unit

• Converting yards to feet

• Subtracting the house's width

• Adding all side lengths
