This can be solved using both the statements.

As from statement I, we know that L × B = 48 or B = L/48.

From statement II, we have,

L2 + B2 = 100.(using pythagoras theorem)

or, L2 + (L/48)2 =100.

L is the only unknown in this equation and can be found out.

L= 99.95661 = 100

L = 10

Option A is the Correct Answer.
