Perimeter = (4x + 12)
Step-by-step explanation:
As given in the question itself,
"Perimeter of a polygon is the sum of measures of all the sides of the polygon."
By this property expression to calculate the perimeter of the given polygon will be,
Perimeter = x + x + x + 2 + 2 + (x + 4) + 2 + 2
= 3x + 4 + (x + 4) + 4
= 4x + 12
Hence, Perimeter = (4x + 12)
