Quizplus · Accepted Answer

The perimeter of a square is found by multiplying the length of one side by 4. 
Therefore, the perimeter of the square picture frame is:
P = 21.1 x 4
P = 84.4 inches 
Thus, the best choice is D with the correct perimeter value. The perimeter of a square is equal to four times the length of one side. Therefore, the perimeter of the square picture frame is 4 times 21.1 inches, which is 84.4 inches. Thus, the correct answer is D.
