Perimeter
A perimeter is a path that encompasses/surrounds a two-dimensional shape.
The term may be used either for the path, or its lengthin one dimension. It can be thought of as the length of the outline of a shape. The perimeter of a circle or ellipse is called its circumference. Calculating the perimeter has several practical applications. A calculated perimeter is the length of fence required to surround a yard or garden. The perimeter of a wheel/circle (its circumference) describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter; if the length of the string was exact, it would equal the perimeter. |

Perimeter Definition
Perimeter is the distance around a two-dimensional object. You can also measure the perimeter of three-dimensional objects like houses, stadiums, buildings and similar shapes. Perimeter is the sum of the measure of every side of a 2D shape, or the sum of the measure of every side of a 3D shape measuring on the ground or floor. Round shapes (ovals, circles, ellipses and such) have perimeter, but we almost always call that measure circumference. Perimeter is always a linear measure. Use the same units given for each side, like mm, foot, and so on. https://tutors.com/math-tutors/geome...efinition-math 01 กุมภาพันธ์ 2021 11:49 : ข้อความนี้ถูกแก้ไขแล้ว 1 ครั้ง, ครั้งล่าสุดโดยคุณ share |
