tolong dibntu pake cara

Panjang :
p = p ÷ s
p = 25 ÷ 1/80
p = 25 × 80
p = 2.000 cm
p = 20 m

Lebar :
l = l ÷ s
l = 20 ÷ 1/80
l = 20 × 80
l = 1.600 cm
l = 16 m

Luas :
L = pl
L = 20 × 16
L = 320 m²

Jawaban : d. 320

Maaf Kalau Salah

Luas sebenarnya
p= 1/80 : 25
 = 2000 cm2 = 20 m2
l = 1/80 : 20
 = 1600 cm2 = 16 m2

L= pxl
=20 x 16
=320 cm2 (d)

Semoga membantu
