Understanding Perimeter

What is the perimeter of a shape?

• The diagonal of the shape

• The area inside the shape

• The volume of the shape

• The length around the shape

How do you find the perimeter of a rectangle?

• Subtract the width from the length

• Multiply the length by the width

• Add the length and width

• Add the lengths of all sides

If a rectangle has two sides of 30 feet and two sides of 60 feet, what is its perimeter?

• 240 feet

• 90 feet

• 120 feet

• 180 feet

Why is it important to include units when stating the perimeter?

• To make calculations easier

• To confuse the reader

• To ensure clarity and accuracy

• To make the answer look longer

In a shape with missing side lengths, how can you find the missing length if two sides are equal?

• By multiplying the known lengths

• By subtracting the known length from the total

• By adding the known lengths

• By guessing

If one side of a shape is 8 cm and the other side is 5 cm plus an unknown length, what is the unknown length if both sides are equal?

• 3 cm

• 2 cm

• 5 cm

• 4 cm

What is the perimeter of a shape with side lengths of 12 cm, 3 cm, 5 cm, 8 cm, 4 cm, and 8 cm?

• 30 cm

• 35 cm

• 40 cm

• 45 cm

What should you do if you encounter a shape with missing side lengths while calculating the perimeter?

• Ignore the missing lengths

• Divide the known lengths by two

• Use known lengths to find the missing ones

• Estimate the missing lengths

What is the first step in solving a perimeter problem with missing side lengths?

• Add all known lengths

• Subtract the smallest length

• Identify equal sides

• Multiply the lengths
