Question

26 cm 5 cm 12 cm 10 cm Hitunglah luas bangun gabungan di atas !​

Answer 1

Jawab:

triple pitagoras 10,24,26

alas = 10 cm

tinggi segitiga = 24 cm

sisi miring segitiga = 26 cm

panjang = 24 cm

lebar = 10 cm

tinggi = 12 cm

Luas Bangun Prisma Segitiga Siku siku

= (2 x [tex]\frac{1}{2}[/tex] x a x t) + ((a+b+c) x t prisma)

=  (2 x [tex]\frac{1}{2}[/tex] x 10 x 24 ) +(10+24+26) x 5)

= 240 + 300

= 540  [tex]cm^{2}[/tex]

Luas Bangun Balok

= pl + 2pt + 2lt

=  24x10 + 2x24x12 + 2x10x12

= 240 + 576 + 240

= 1.056 [tex]cm^{2}[/tex]

Luas = 540 + 1.056 = 1.596 [tex]cm^{2}[/tex]
