Answer:

A. 11.2 cm

Step-by-step explanation:

Perimeter of Octagon

To find the perimeter of an octagon, we have to calculate the length of sides of the octagon

length of the side is equal to twice the value of the base of the triangle

[tex]l = 2 * 0.7 = 1.4cm[/tex]

The length of the side of the octagon is 1.4cm

The perimeter of the octagon is

[tex]P = 8 * L\\P = 8 * 1.4 = 11.2cm[/tex]

The perimeter of the octagon is 11.2cm
