Answer:
3x-4
Step-by-step explanation:
Length = x
width = 2 units shorter than half the length x
width = x/2 - 2
For rectangle
perimeter = 2(length + width)
Perimeter for given rectangle = 2(length + width)
Perimeter for given rectangle = 2(x + x/2 - 2) = 2x + 2x/2 -4
Perimeter for given rectangle = 2x+x -4 = 3x -4
Expression that represents the perimeter of the rectangle is 3x-4.
