Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

Materi : Bangun Ruang Sisi Datar

Soal Nomor 2

tst² = (½s)² + t²

tst² = 5² + 12²

tst = √169

tst = 13 cm

---

Lp = s² + 2 . s . tst

Lp = 100 cm² + 2 . 10 cm . 13 cm

Lp = 100 cm² + 260 cm²

Lp = 360 cm²

Soal Nomor 3

4( p + l + t ) = 216 cm

4x + 2x + 3x = 54 cm

9x = 54 cm

x = 6 cm

---

p = 24 cm

l = 12 cm

t = 18 cm

---

Lp = 2( pl + pt + lt )

Lp = 2( 24.12 + 24.18 + 12.18 )

Lp = 2( 288 + 432 + 216 )

Lp = 2( 936 cm² )

Lp = 1.872 cm²

Soal Nomor 4

Lp = at + tp( a + t + s )

Lp = 6.8 + 15( 6 + 8 + 10 )

Lp = 48 cm² + 15 cm × 24 cm

Lp = 48 cm² + 360 cm²

Lp = 408 cm²

Soal Nomor 5

Lp = 2( pt + lt ) + at + tp( a + 2s )

Lp = 2( 10.0,5 + 6.0,5 ) + 6.4 + 10( 6 + 10 )

Lp = 2( 5 + 3 ) + 24 + 160

Lp = 16 + 24 + 160

Lp = 40 + 160

Lp = 200 m²

Semoga bisa membantu
