Question

kiara takes a sheet of paper and makes a diagonal cut from one corner to the opposite corner, making two triangles. the cut she makes is 20 centimeters long and the width of the paper is 12 centimeters. what is the paper's length?

Answer 1

16 inches

Explanation:

Use the Pythagorean Theorem (a²+b²=c²) and rearrange it: c²-a²=b². Substitute your values in to have: 20²-12²=b² → 400-144=√256 → √256 = 16.
