Find the perimeter of the square:
◻️ 5x-7
a. 25x^2-49
b. 20x-28
c. 25x^2-70x+49
d. 10x-14
The perimeter of a square is found by adding up the lengths of all four sides. In this case, all four sides of the square are equal to 5x-7.
Perimeter = (5x-7) + (5x-7) + (5x-7) + (5x-7)
= 4(5x-7)
= 20x - 28
Therefore, the correct answer is option b. 20x-28.
