Question

question: find the perimeter of the figure below, in centimeters. (note: diagram is not to scale)

Explanation:

Step1: Identify horizontal side - lengths

Sum the horizontal side - lengths. The horizontal lengths are: \(27.4 + 8.7+12.8 + 12.8+8.7+27.4 = 97.8\) cm.

Step2: Identify vertical side - lengths

Sum the vertical side - lengths. The vertical lengths are: \(34.3+12.8 + 14.6+12.8+21.5+12.8 = 118.8\) cm.

Step3: Calculate the perimeter

The perimeter \(P\) of the figure is the sum of all the outer - side lengths. So \(P=(97.8 + 118.8)=216.6\) cm.

Answer:

216.6 cm
