Given values:

Reading at the left end (L) = 5 cm

Reading at the right end (R) = 21 cm

The length of the metal rod (D) can be calculated by subtracting the reading at the left end from the reading at the right end:

                    D = R - L

Step 1: Calculate the length of the metal rod:

                    D = 21 cm - 5 cm = 16 cm

The length of the metal rod is 16 cm.

The length of the metal rod is calculated to be 16 cm or 160 mm.
