B
C
Step 1: In the figure, PQ = 5 units and QR = 4 units.
Step 2: PQR is a right triangle and PR is the hypotenuse.
Step 3: Applying Pythagorean theorem for ΔPQR, PR2 = PQ2 + QR2.
Step 4: PR2 = 52 + 42.[Substitute PQ = 5 and QR = 4.]
Step 5: PR2 = 25 + 16 = 41.
Step 6: PR = √41[Take square root on both the sides.]
Step 7: So, the length of the side PR is √41 units.
