jawab y makai cara jawab semuanya thanksss :)

24.
K = S+S+S+S
= 23+20+16+12
= 71 (A. 71 cm)

25.
K = π×d
= 22/7×42
= 22×6 = 132 (C. 132 cm)

26.
L. 1/2 lingkaran = π×r2×1/2
= 3,14×8pangkat 2×1/2
=3,14×64 = 200,96×1/2
=100,48
L. persegi panjang = P×L
= 30×16 = 480

jadi 100,48 + 480 = 580,48 ( C. 580,48 cm2)

semoga membantu :)
