## FAQs on Perimeter of Regular Shapes: Square and Triangle Video Lecture - Mathematics (Maths) Class 6

 1. What is the formula to calculate the perimeter of a square?
Ans. The formula to calculate the perimeter of a square is 4 times the length of one side of the square. So, if the length of one side is 's', then the perimeter of the square is given by the formula 4s.
 2. How do you find the perimeter of a triangle?
Ans. To find the perimeter of a triangle, you need to add the lengths of all three sides of the triangle. If the lengths of the three sides are 'a', 'b', and 'c', then the perimeter is given by the formula a + b + c.
 3. Is the perimeter of a square and a triangle always the same?
Ans. No, the perimeter of a square and a triangle is not always the same. The perimeter of a square depends on the length of one side, while the perimeter of a triangle depends on the lengths of all three sides. Therefore, the perimeters of these two shapes will be different unless the lengths of the sides are equal in both shapes.
 4. Can a triangle have a perimeter of zero?
Ans. No, a triangle cannot have a perimeter of zero. The perimeter of a triangle is the sum of the lengths of its sides, and all sides of a triangle have to have a positive length. Therefore, the minimum perimeter of a triangle would be the sum of the lengths of the smallest non-zero sides.
 5. How can I find the perimeter of an irregular triangle?
Ans. To find the perimeter of an irregular triangle, you need to measure the lengths of all three sides using a ruler or measuring tape. Once you have the lengths of the sides, you can simply add them together to find the perimeter.
