What would be the SUM of the lengths of the first and second diagonals rounded to the nearest whole number?

16 m

Step-by-step explanation:

Use Pythagorean theorem,

hypotenuse² = base² +altitude²

                      = 5² +6²

                      = 25 + 36

                      = 61

First diagonal = = 7.81 m

Second diagonal² = first diagonal² + altitude²

                              =  + 3²

                              = 61 + 9

                              = 70

second diagonal = = 8.37 m

First diagonal  + second diagonal = 7.80 + 8.37 = 16.17 = 16
