[tex] t = \dfrac{V}{p \times l} [/tex]

[tex] t = \dfrac{\cancel{1.560}}{ \cancel{20} \times 6} [/tex]

[tex] t = \dfrac{\cancel{78}}{\cancel{6}} [/tex]

[tex] t = \bold{13} [/tex]

Lp = 2(p × l) + (p × t) + (l × t)

Lp = 2(20 × 6) + (20 × 13) + (6 × 13)

Lp = 2(120 + 260 + 78)

Lp = 2(380 + 78)

Lp = 2(458)

Lp = (2 × 458)

Lp = 916 cm² (a.)
