Question

A 24.72 meter distance will be laid out using a 50 m tape that is .12 m too long. Where on the tape would you put the mark in order to layout the required 24.72 meter?

Answer 1

Corrected tape length (L)=50m

corrected length to be measured(l) =24.72m

incorrect tape length (L') =50+0.12

=50.12 m

mark required on tape(l')=?

Now,

L x l = L' x l'

50x24.72 = 50.12 x l'

mark is to be put at l'=24.6608m
