Answer:
b = 1.52
Step-by-step explanation:
Length of diagonals of a parallelogram = 
and 
If the given parallelogram is a rectangle,
Length of the diagonals will be equal in measure,
Therefore, 
245b - 365 = 
245b - 365 = 
5(245b - 365) = 4(3b + 6)
1225b - 1825 = 12b + 24
1225b - 12b = 24 + 1825
1213b = 1849
b = 
b = 1.52
