FAQs on Perimeter and Area of Plane Figures - 1 Video Lecture - Mathematics Class 6 ICSE

1. What is the difference between perimeter and area?
Ans. The perimeter is the total length of the edges of a plane figure, while the area measures the space enclosed within that figure. For example, for a rectangle, the perimeter is calculated by adding the lengths of all four sides, whereas the area is found by multiplying the length by the width.
2. How do you calculate the perimeter of a rectangle?
Ans. To calculate the perimeter of a rectangle, you use the formula: Perimeter = 2 × (Length + Width). Simply add the length and width together, then multiply by 2 to get the total perimeter.
3. What formula do you use to find the area of a triangle?
Ans. The area of a triangle can be calculated using the formula: Area = 1/2 × Base × Height. You take the length of the base, multiply it by the height (the perpendicular distance from the base to the opposite vertex), and then divide the result by 2.
4. Can the perimeter of a shape be the same as its area?
Ans. Yes, it is possible for a shape to have the same numerical value for its perimeter and area, but this usually occurs in specific cases. For example, a square with a side length of 4 units has a perimeter of 16 units and an area of 16 square units.
5. What is the area of a circle and how is it calculated?
Ans. The area of a circle is calculated using the formula: Area = π × r², where "r" is the radius of the circle. You square the radius (multiply it by itself) and then multiply by π (approximately 3.14) to find the area.
