Exploring Perimeter Calculations for Rectangles

Mr. Ahmed introduces the concept of perimeter, focusing on rectangles and squares. He explains how to calculate perimeter using both addition and multiplication, providing examples with a garden and various shapes. The lesson covers formulas for perimeter, including the use of the distributive property to simplify calculations. Students are encouraged to practice these concepts through examples and are provided with a summary of the key points.

What is the perimeter of a rectangle with a length of 7 feet and a width of 5 feet?

• 35 feet

• 12 feet

• 10 feet

• 24 feet

Which operation is primarily used in calculating the perimeter of geometric shapes?

• Multiplication

• Division

• Addition

• Subtraction

How do you calculate the perimeter of a rectangle using its length and width?

• Add twice the length and twice the width

• Subtract length from width

• Multiply length by width

• Add length and width

What does the 'P' stand for in the perimeter formulas?

• Point

• Perimeter

• Polygon

• Product

What formula represents the perimeter of a rectangle?

• P = 2L + 2W

• P = L * W

• P = L + W

• P = 2(L + W)

Using the distributive property, how can the perimeter formula be rewritten?

• P = L + W

• P = L * W

• P = 2(L + W)

• P = L - W

What is the perimeter of a square with a side length of 4 meters?

• 12 meters

• 4 meters

• 8 meters

• 16 meters

How can the perimeter of a square be calculated?

• Multiply one side by 4

• Add all four sides

• Multiply one side by 2

• Divide one side by 4

If a rectangle has a length of 8 feet and a width of 4 feet, what is its perimeter using the formula 2(L + W)?

• 24 feet

• 16 feet

• 12 feet

• 32 feet

What is the perimeter of a rectangle with lengths of 110 meters and 42 meters using the formula P = 2(L + W)?

• 202 meters

• 254 meters

• 152 meters

• 304 meters
