Given length = 5.55 inches

Width = 1.9 inches

We need to find the perimeter of the regular face using the given data. Generally cell phone is in rectangular shape.

Perimeter of a rectangle can be found out by using the below formula,

P = 2(l + w)

Where  

l is the length of the rectangle

w is the width of the rectangle

p = 2(5.55+1.9)  = 14.9

The perimeter of the regular face is 14.9. inches
