Tolong di jawab kak yg no 4 dan lima nya yg di coret itu gak kak​

Jawab:

4. c. K = 2(p + l)

100 = 2 (30 + l)

100 / 2 = 30 + l

50 = 30 + l

l = 50 – 30

l = 20 cm

d. K = 2(p + l)

136 = 2 (p + 26)

136 / 2 = p + 26

68 = p + 26

p = 68 – 26

p = 42 cm

5. a. K = 7 + 15 + 22

= 44 cm

b. K = 20 + 32 + 32

= 84 cm

c. K = 35 + 35 +35

= 105 cm
