The steel tape shown is used to lay
out the distance from point A to
point B.

At another time, the steel tape
shown is used to measure the
distance from point A to point B,

add or subtract to the measurement
in order to compensate for the
change in temperature?

2.
Subtract 0.02 ft
3.
Add 0.04 ft
4.
Subtract 0.04 ft
