| KillGorack | 2023-06-18 19:03:51 | For 18 cm: 49 cm² + 18 cm² = 67 cm² (not equal to 625 cm²). Not a valid option. For 24 cm: 49 cm² + 24 cm² = 625 cm². This option satisfies the Pythagorean theorem and could be the length of the third side. For 27 cm: 49 cm² + 27 cm² = 730 cm² (not equal to 625 cm²). Not a valid option. For 32 cm: 49 cm² + 32 cm² = 1185 cm² (not equal to 625 cm²). Not a valid option. For 20 cm: 49 cm² + 20 cm² = 629 cm² (not equal to 625 cm²). Not a valid option. |
