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

$P=4b$

where

b is the length side of the square

we have

$P=(80-64y)\ units$

substitute the given value in the formula

$(80-64y)=4b$

solve for b

Divide by 4 both sides

$(20-16y)=b$

Rewrite the expression

$b=(20-16y)\ units$

<em>Alternative Method</em>

we have

$P=(80-64y)\ units$

Factor 4

$P=4(20-16y)\ units$

Each side measures (20-16y) units.
