Find the perimeter of a regular pentagon
WebThe apothem of a pentagon is the perpendicular distance from the center of the pentagon to the center of one of its sides. The apothem can also be considered as the radius of the incircle of a polygon. The apothem is used mainly to calculate the area of a regular polygon. Here, we will learn how to calculate the apothem of a pentagon.

WebOct 24, 2024 · A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value: P = 5(3x +5) Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5: P = 15x + 25 WebAll the five sides of regular pentagon are equal. So, Length of each side of regular pentagon = 16cm Perimeter of regular pentagon = ( 5 x Length of each side ) units = ( 5 x 16 ) cm = 80 cm. Question 3.
