Question

find the perimeter. include the unit. 14 cm 14 cm 13 cm 12 cm 8 cm

Explanation:

Step1: Recall the formula for perimeter

The perimeter \(P\) of a polygon is the sum of the lengths of all its sides. So, \(P = a + b+ c + d+e\) where \(a,b,c,d,e\) are the side - lengths.

Step2: Substitute the side - lengths

Here, \(a = 14\space cm\), \(b = 13\space cm\), \(c = 8\space cm\), \(d = 12\space cm\), \(e = 14\space cm\). Then \(P=14 + 13+8 + 12+14\).
First, add \(14+13 = 27\), then \(27+8=35\), then \(35 + 12=47\), and finally \(47+14 = 61\).

Answer:

\(61\space cm\)
