Materi : Perbandingan dan Skala
p : l = 7 : 2 = 7x : 2x
________________/
L = 504 m²
pl = 504 m²
(7x)(2x) = 504
(7x)(x) = 252
(x)(x) = 36
x² = 36
x = √36
x = 6 m
____________/
Panjang = 7x = 42 m
Lebar = 2x = 12 m
Keliling = 2( p + l ) = 2( 54 m ) = 108 m
Semoga bisa membantu

P=7x cm
L=2x cm
504=P×L
504=7x.2x
504=14x²
x²=504/14
x²=36
x=√36=6cm
Jadi panjang dan lebar
7x=7×6=42cm
2x=2×6=12cm
Keliling:
2(42+12)=2(54)=108
Semoga bermanfaat
