Jawaban:
2. K = 48 cm
3. K = 18 cm
4. p = 10 cm
5. l = 11 cm
Jawaban:
Cara :
[tex]k = 2 \times (p + l)[/tex]
2. p = 15 cm
l = 9 cm
[tex]k = 2 \times (15 + 9) = 48 \: cm[/tex]
3. p = 5 cm
l = 4 cm
[tex]k = 2 \times ( 5 + 4) = 18 \: cm[/tex]
4. k = 36 cm
l = 8 cm
[tex] p = (k \div 2) - l[/tex]
[tex] p = (36 \div 2) - 8[/tex]
[tex] p = 10 cm[/tex]
5. k = 50 cm
p = 14
[tex]l = (k \div 2) - p[/tex]
[tex]l \: = (50 \div 2) - 14[/tex]
[tex]l = 11 \: cm[/tex]
semoga membantu
