luas suatu jajargenjang adalah 504 cm kubik jika alas : tinggi = 7 : 2 maka panjang alasnya adalah
![]()
Jawaban:
L = a × t
L = a × t504 = 7x × 2x
L = a × t504 = 7x × 2x504 = 14x²
L = a × t504 = 7x × 2x504 = 14x²14x² = 504
L = a × t504 = 7x × 2x504 = 14x²14x² = 504 x² = 504
L = a × t504 = 7x × 2x504 = 14x²14x² = 504 x² = 504 14
L = a × t504 = 7x × 2x504 = 14x²14x² = 504 x² = 504 14 = 36
L = a × t504 = 7x × 2x504 = 14x²14x² = 504 x² = 504 14 = 36x = √36 = 6 cm
L = a × t504 = 7x × 2x504 = 14x²14x² = 504 x² = 504 14 = 36x = √36 = 6 cm maka tinggi jajargenjang = 2x = 2 × 6 = 12 cm
Jawaban:
144
Penjelasan dengan langkah-langkah:
p.jajar genjang:
[tex]p = \frac{luas}{a \div t } = p = \frac{504}{7 \div 2} = \frac{504}{3.5} = 144[/tex]
maaf ya kalo salah
