.

Let x be the length. Then the perimeter is x + 19 + x + 19 = 2x+38, and it must be >= 150 cm: 2x + 38 >= 150. To solve this inequality, subtract 38 from both sides. You will get 2x >= 150 - 38 = 112. Next divide both sides by 2. You will get x >= = 56. Answer. The length must be >= 56 cm. The photo must be 56 cm or longer. Not shorter.
