Verified answer
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
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
