Question

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

Explanation:

Step1: Identify side - lengths

The figure has 4 sides of length 9.3 m and 4 sides of length 12.1 m.

Step2: Calculate perimeter formula

The perimeter $P$ of a polygon is the sum of the lengths of its sides. So $P = 4\times9.3+4\times12.1$.

Step3: Calculate 4 times 9.3

$4\times9.3 = 37.2$.

Step4: Calculate 4 times 12.1

$4\times12.1=48.4$.

Step5: Sum the results

$P=37.2 + 48.4=85.6$ m.

Answer:

85.6 m
