14. 39538.png

The length of each side of the square above is 395281.png + 1. The perimeter of the square is

  • A. 39519.png + 4
  • B. 39507.png
  • C. 39498.png + 4
  • D. 39487.png + 16

Correct Answer: A

Explanation:

The correct answer is (A). The figure is a square, so all four sides are equal in length. The perimeter is the sum of the lengths of the four sides.

Each side is 38593.png + 1.

The sum, then, is 38582.png + 38570.png + 38561.png + 38552.png = 38542.png + 4.

You could also multiply 385331.png + 1 by 4 for the same result.
