d) 48 m
bantuin dong kk kk yg bisa pake cara yaa
Penjelasan dengan langkah-langkah:
panjang sisinya
L = s²
s = √144
s = 12 m
maka, kelilingnya
k = 4s
k = 4.12
k = 48 m (d)
SOAL 1
___________________________________________
S Persegi = √L Persegi
S Persegi = √144
S Persegi = √12²
S Persegi = 12 m
___________________________________________
K Persegi = 4 × S Persegi
K Persegi = 4 × 12
K Persegi = 48 m
