A rectangle has a diagonal of 2 and a length of 13. Find its width.

The width is or 12.8452326i units long.

Step-by-step explanation:

Well the diagonal and length make a Pythagorean triangle with the width as a or b.

13²+b²=2²

169+b²=4

Subtract 169 from both sides.

b²=-165

Square root both sides

b=≈12.8452326i

First simplify  130=_5x2x13_ 13
                     400=  2x2x5x4x4   32
 now convert:        __0.4__                    
                         32l13.0
                          --  128
                                       so 0.4 is the answer
                              00.2
