Question

calculate the perimeter of a square whose area us 25^2 + 20x +4​

Answer 1

Answer:

20x + 8

Step-by-step explanation:

$25x^{2} + 20x + 4\\= (5x)x^{2} + (2)(5x)(2) + 2x^{2} \\= (5x + 2)^{2}$

∴ The side of the square is (5x + 2)

  Perimeter of square = 4s

  s = (5x + 2)                 = 4 (5x + 2)  

                                     = 20x + 8
