A. 16(5-4y).Each side measures 5-4y units
B. 16y(5-4y) Each side measures 5-4 y units
C. 4(20-16y)Each side measures 20-16y units
D 4y(20-16)Each side measures 20-16 units ​

Answer 1

Option C is correct

4(20-16y) each side measures 20-16y units

Explanation:

The distributive property says that:

The perimeter(P) of a square is given by:

.....[1]

As per the statement:

The perimeter of a square is 80-64y units

we can write this as:

Apply the distributive property we have;

⇒P = 4(20-16y)

On comparing with [1] we have;

Each Side length = 20-16y units

Therefore, an expression can be used to show the side length of one side of the square is, 4(20-16y) each side measures 20-16y units

Answer 2
