Correct : 22

The temperature correction in tape measurement accounts for the expansion or contraction of the tape relative to its standardisation temperature. The correction formula is:
C_t = α × (T − T₀) × L
where α is the coefficient of expansion, T is the field temperature, T₀ is the standardisation temperature, and L is the measured length.
Substituting values:
C_t = 11 × 10⁻⁶ × (35 − 25) × 200 = 11 × 10⁻⁶ × 10 × 200 = 0.022 m = 22 mm
Since the field temperature (35°C) is higher than the standardisation temperature (25°C), the tape has expanded, meaning the actual length measured is slightly more than what the tape readings suggest — this is a positive correction that must be added to the measured length to get the true distance.
