LT = LO + LO . ALFA . DELTA T.
LT = 100 + 100 . 0.000017 . 200 =
100 + (100 . 0.000017 . 200 ) 
= 100 + (1 . 0.017 x 2 )
= 100 + 0.034 = 100.034
Semoga membantu,ya!

Α   = 1,7 . 10⁻⁵
Lo = 100 cm = 1 m (satuan nya meter)
L ?
ΔT = 200
L = Lo(1+αΔT)
L = 1 (1+1,7.10⁻⁵.200)
L = 1 (1+0,0034)
L = 1,0034 m
