Jawaban: 6cm x 2cm

Penjelasan:

Mengingat bahwa poster tersebut ditarik pada skala 1: 4

Interpretasi skala:

1: 4 = 1 cm dari gambar yang diambil mewakili 4 cm dari ukuran sebenarnya dari gambar

Oleh karena itu 1cm pada gambar mewakili 4cm dalam kenyataan.

Karena itu, jika poster berukuran 24 cm kali 8 cm, gambar poster dengan skala 1: 4

Kemudian, menggambar akan menjadi (24cm x 8cm) / 4

Panjang gambar adalah (1/4) * 24cm = 6cm

Lebar gambar adalah (1/4) * 8cm = 2cm

(6cm kali 2cm)
