25.) What is the length of the longest line segment you can draw on a sheet of paper that is 27.9 by 21.6? Express your answer to the nearest tenth of a centimeter.
1.) First you would need to square both the numbers.27.9 cm² = 778.41
21.6 cm² = 466.56
2.) Add them together.
778.41 cm² + 466.56 cm² = 1,244.97
3.) Find the square root of 1,244.97
√1,244.97 = 35.28 cm
4.) Round to the nearest tenth of a centimeter.
35.28 cm rounded to the nearest centimeter would be 35.3 cm.
The length of the longest line segment would be 35.3 cm.
