Tolong dibantu ya itu cari keliling nya, angka (sisi) nya itu 8cm.
Zuhh
> keliling bangun 1 (persegi) = 4 x sisi = 4 x 8 = 32 cm Luas bangun 1 = sisi x sisi = 8 x 8 = 64 cm²
> keiling bangun 2 (persegi panjang), dik panjang = 16 cm lebar = 8 cm K = 2 x (p + l) = 2 x (16 + 8) = 2 x 24 = 48 Luas bangun 2 = p x l = 16 x 8 = 128 cm²
jadi keliling total = 48 + 32 = 80 cm Luas total = 64 + 128 = 192 cm²
= 4 x 8 = 32 cm
Luas bangun 1 = sisi x sisi = 8 x 8 = 64 cm²
> keiling bangun 2 (persegi panjang),
dik panjang = 16 cm
lebar = 8 cm
K = 2 x (p + l)
= 2 x (16 + 8)
= 2 x 24
= 48
Luas bangun 2 = p x l
= 16 x 8
= 128 cm²
jadi keliling total = 48 + 32 = 80 cm
Luas total = 64 + 128 = 192 cm²
