To find the perimeter of any shape, the outside edges of the shape should be added together. The perimeter is defined as the distance that is around the outside of a two dimensional shape.Know More
There are certain formulas that can make finding the perimeter of different shapes easier and more efficient. To find the perimeter of a triangle, all three sides should be added together. To find the perimeter of a square, the length of one side can be multiplied by 4. To find the perimeter of a rectangle, the length and width can be added together and multiplied by 2. Since a quadrilateral does not have sides that are equal to each other, each of the sides should be added together individually.
The perimeter of a circle is called the circumference. The radius of a circle is half of a line through the middle of the circle. To find the circumference, the radius should be multiplied by pi and then multiplied by 2. A sector is a section of a circle that is defined by degrees in radians. To find the perimeter of a sector, the angle of the sector should be added to 2 and should be multiplied by the radius of the circle.Learn more about Shapes
If the perimeter of a rectangle is known, finding the width is only possible if the length is also known. Infinite combinations of lengths and widths of a rectangle exist with any given perimeter.Full Answer >
To find the perimeter of a triangle, use the equation P=A+B+C, where P is the perimeter and A, B and C are the lengths of each of the three sides of a triangle. The perimeter of a triangle is the distance around all three sides.Full Answer >
To find the perimeter of a polygon, add the lengths of each side together. The sum is the total perimeter.Full Answer >
To find the perimeter of a circle, also known as the circumference, plug the dimensions of the circle into the formula ((pi)(d). This formula stands for pi (approximately 22/7) times the diameter of the circle (d).Full Answer >
