## Calculate the Horizontal Length After Slope Correction of the Tape

**Mathematical Problem:**

The downhill end of the 30m tape is held 70cm too low. What is the horizontal length?

**Solution:**

Given,

l = Length of the tape = 30 m.

h = 70 cm = 0.70 m

Correction for slope = = = 0.00817 m.

Hence, the horizontal length = 30 – 0.00817 = 29.99183 m
