Understanding Perimeter in Standard Units

This video tutorial teaches how to find the perimeter of various objects by adding the lengths of their sides. It begins with an introduction to the concept of perimeter, followed by practical examples including a rectangular table, a sign board model, and a swimming pool design. Each example demonstrates the step-by-step process of calculating the perimeter by summing the measurements of all sides, reinforcing the concept's application in real-life scenarios.

What is the perimeter of an object?

• The distance around the object

• The volume of the object

• The height of the object

• The area inside the object

Why is understanding perimeter important in everyday life?

• It is necessary for understanding algebra

• It is only important for architects

• It is used in measuring distances around objects

• It helps in calculating volume

How do you calculate the perimeter of a rectangle?

• Multiply the length by the breadth

• Add all the sides together

• Subtract the breadth from the length

• Add the length and breadth

If a table has a length of 3 meters and a breadth of 1 meter, what is its perimeter?

• 6 meters

• 4 meters

• 10 meters

• 8 meters

What is the first step in finding the perimeter of a sign board model?

• Measure the area of the sign board

• Add the lengths of all the sides

• Multiply the lengths of the sides

• Subtract the smallest side from the largest

If a sign board has sides measuring 30 cm, 20 cm, 25 cm, 25 cm, and 20 cm, what is its perimeter?

• 130 cm

• 100 cm

• 110 cm

• 120 cm
