Tolong dijawab juga karena ulangan nanti folow kalo udh jawab​

5. k= 2 x (p+l)

= 2 x (10+8)

= 2 x 18

= 36 cm (A)

6. p = (K ÷ 2) – l

p= (76 : 2) – 18

p=38 – 18

p= 20 cm (B)

7. L= (k : 2) – p

L= (120 : 2) – 35

L=60 – 35

L= 25 cm (C)

8. Kpersegi panjang: 2 x ( p + l)

= 2 x (20 cm + 16 cm)

= 2 x 36 cm

= 72 cm

Kpersegi = 72 cm

sisi persegi = 72 cm : 4

= 18 cm (D)
