the base of the right triangle drawn in the regular octagon measures 0.7 cm. what is the perimeter of the…

Explanation:

Step1: Recall property of regular octagon

In a regular octagon, the right - triangle drawn from the center to a side is such that the base of the right - triangle is half of the side length of the octagon.

Step2: Calculate side length of octagon

If the base of the right - triangle is $0.7$ cm, then the side length $s$ of the regular octagon is $s = 2\times0.7=1.4$ cm.

Step3: Calculate perimeter of octagon

The perimeter $P$ of a regular octagon with side length $s$ is given by $P = 8s$. Substituting $s = 1.4$ cm, we get $P=8\times1.4 = 11.2$ cm.

Answer:

11.2 cm
