Ayoo tolong bantu!! Kalo bisa semua ku follow + ku jadikan jawaban terbaik. Poin lumayan​

Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

1.) K = 2 ( p + l ) = 32

P = 2L

K = 2 ( 2L + L ) = 32

K = 2 ( 3L ) = 32

K = 6 L = 32

L = 5,3

Maka luas = p x l

= 28 × 5,3

= 148,4

Maka luas max = 148,4 cm

2.)Jika panjang = 2 Kali lebar

Maka p = 2L

Maka

P x L = 36

2L x L = 36

Lkuadrat = 36

L = 6

P =2. L

= 2. 6

= 12

Maka keliling = 2 ( 6 + 12 )

= 36

Maka keliling max = 36 cm

3 ) k = 30 cm = 2 ( p + l )

= 2 ( 2L + L ) = 30

= 6L = 30

L = 5 cm

P = 2. 5 = 10

Maka Luas max = 5 x 10 = 50 cm
