Penjelasan dengan langkah-langkah:
Lp = 2 × ((p × l) + (p × t) + (l × t))
516 = 2 × ((15 × 6) + (15 × t) + (6 × t))
516 = 2 × (90 + 15t + 6t)
516 = 2 × (90 + 21t)
516 = 180 + 42t
42t = 516 - 180
42t = 336
t = 8 Cm
LP = 2 × ( ( p × l + ( p × t ) + ( l × t ) )
516 = 2 × ( ( 15 × 6 ) + ( 15 × t ) + ( 6 × t ) )
516 = 2 × ( 90 + 21t )
516/2 = 90 + 21t
258 = 90 + 21t
21t = 258 - 90
21t = 168
t = 168/21
t = 8 cm.
