I saw the image that should accompany this problem. It is a rectangular prism and the base has a right triangle with a measure of the following: long leg = 18cm ; short leg = 16cm
We need to look for the hypotenuse because it serves as the long leg of the right triangle where AG is the hypotenuse.
base triangle a² + b² = c² (16cm)² + (18cm)² = c² 256cm² + 324cm² = c² 580 cm² = c² √580cm² = √c² 24 cm = c
2nd triangle: long leg = 24cm ; short leg = 16cm (24cm)² + (16cm)² = c² 576 cm² + 256 cm² = c² 832 cm² = c² √832 cm² = √c² 28.8 cm = c
