Answer:

Option C. 4(20-16y): Each side measures 20-16y units.

Step-by-step explanation:

we know that

The perimeter of a square is equal to

[tex]P=4b[/tex]

where

b is the length side of the square

we have

[tex]P=(80-64y)\ units[/tex]

substitute the given value in the formula

[tex](80-64y)=4b[/tex]

solve for b

Divide by 4 both sides

[tex](20-16y)=b[/tex]

Rewrite the expression

[tex]b=(20-16y)\ units[/tex]

Alternative Method

we have

[tex]P=(80-64y)\ units[/tex]

Factor 4

[tex]P=4(20-16y)\ units[/tex]

so

Each side measures (20-16y) units.
