Question

Tolong pake cara ya sma Rumusnya klau ada...mksihh...;);)

Answer 1

2) Lp limas = L alas + jumlah L sisi tegak
= s² + 4.1/2.a.t
= 2² + 4.1/2.2.2,5
= 4 + 10
= 14 m²


3) Lp limas tanpa alas = jumlah L sisi tegak
45√5 = 4.1/2.a.t
45√5 = 2.6.t
45√5 = 12.t
t = 45√5 : 12
t = 45/12√5
t = 45/12.2,24
t = 45/26,88 = 1,67 cm
