Question

The area of a square is 16x^2 -40x+ 25. What is the perimeter of the square?​

Answer 1

Perimeter = 16x-20 units

Explanation:

Given: 16x^2 - 40x + 25

Reduce perfect square trinomial: (4x-5)(4x-5)

4x-5 is your side length. Since the perimeter of a square is 4s, then the perimeter is 4(4x-5)=16x-20
