Tolong ya kak…. pake caranya juga ​

Jawaban:

p= 24 m

l = 18 m

Penjelasan dengan langkah-langkah:

p + l = 1/2 K = 1/2 x 84 m = 42 m

misal panjang = x

maka lebar = x-6

p + l = 1/2 K

x + (x – 6) = 42

x + x – 6 = 42

2x = 42 + 6

2x = 48

x = 48/2 = 24

jadi

p= 24 m

l = x – 6 = 24 – 6 = 18m
