Write a formula for the perimeter of a regular heptagon (7 sides). Evaluate for a side of 12 in.

P = 6x; 72 in.
P = 7x; 84 in.
P = 7x; 86 in.
P = 8x; 96 in.

Question

Write a formula for the perimeter of a regular heptagon (7 sides). Evaluate for a side of 12 in.  

    P = 6x; 72 in.
    P = 7x; 84 in.
    P = 7x; 86 in.
    P = 8x; 96 in.

anonymous · Answer

second option. .

formula for regular heptagon perimeter = s(n) 
            where s= measure of the side
                      n=number of sides
     therefor P=sn
                   =7(12)
                   =84
