tinggi segitiga = √8²+6² = 10
Lp = L Alas + 4 luas sisi tegak
= 144 + 4(1/2 x a x t)
=144 + 4 (1/2 x 12 x 10)
=144 + 240
=384 cm²
mka
La = 144 cm²
⇒ s² = 144
⇒ s = √144
⇒ s = 12 cm
maka tinggi sisi tegak
⇒ t² = (1/2 · s)² + T²
⇒ t² = (1/2 · 12)² + 8²
⇒ t² = 6² + 8²
⇒ t² = 36 + 64
⇒ t² = 100
⇒ t = √100
⇒ t = 10 cm
maka
Lp = s² + 4(1/2)(s)(t)
= 12² + 2(12)(10)
= 144 + 240
= 384 cm²
V = (1/3)(s²)(T)
= (1/3)(12)(12)(8)
= 384 cm³
