The area of a square in square feet is represented by z² + 8z + 16.

Luden [163]

Answer:

Side length: z + 4

Perimeter: 64

Step-by-step explanation:

Hello!

Since the area of a square is the square of the sde length,

using the special binomial product formula: (a+b)² = a² + 2ab + b²:

z² + 8z + 16
(z + 4)²

The side length of the square is (z+4)².

The perimeter is 4(z + 4), where z is 12:

4(12 + 4)
4(16)
64

The side length is z + 4, the perimeter is 64
