Answer 1

the diagonals of rhombus bisects each other by 90°

then

5²=(8/2)²+ half of II diagonal²

25-16= half of II diagonal²

9= half of II diagonal²

3=half of II diagonal

6=second diagonal

Answer 2

Side = 5 cm
One diagonal = 8 cm
Length of other diagonals = (5)sq - (4)sq = 25 - 16 =9
9 is sq root of 3.
Length will 6 cm
