pa basuki memiliki kebun tanaman singkong dengan keliling 112 meter kalau lebarnya 16 meter berapa panjang kebun pak basuki dan luas kebun pak basuki ?

K = 2p + 2l
112 = 2p + 2(16)
112 = 2p + 32
2p = 112 - 32
2p = 80
p = 40 m

Maka,
Luas = pl
= 40 x 16
= 640 m²

Please, let me answer your question :)

Pembahasan :

Diketahui :
- K = 112 m
- l = 16 m

Ditanya :
- Panjang
- Luas

K = 2 x (p + l)
112 = 2 x (p + 16)
p + 16 = 112/2
p + 16 = 56
p = 56 - 16
p = 40 m

L = p x l
L = 40 x 16
L = 640 m²

Jawaban :
- p = 40 m
- L = 640 m²
