Question

The length of each of the sides of a heptagon are 2x - 1. Which equation can be used to find p, the perimeter of the heptagon?

Answer 1

Answer: D. p = 14x - 7

Step-by-step explanation:

A heptagon has 7 sides. Since each side is 2x-1 units long, this means,

perimeter = (number of sides)*(length of each side)

p = 7*(2x-1)

p = 7*(2x) + 7*(-1)

p = 14x - 7

Answer 2

B. p = 14x - 7

Step-by-step explanation:

a heptagon has 7 sides then

p = 7×(2x - 1) = 14x - 7
