Boleh bntu gaa??soal mtk!!!!!jan ambil poinnya doang​

Penjelasan dengan langkah-langkah:

keliling gabungan

= 1/2×πd + s+s + s+s + s

= 1/2×22/7×(24-5-5) + 5+5 + 30+30 + 24

= 1/2×22/7×14 + 10 + 60 + 24

= 22 + 94

= 116 (opsi D)

Penjelasan dengan langkah-langkah:

k lingkaran :

= 1/2πd

= 1/2 x 22/7 x (s persegi – sisi pinggir.2)

= 1/2 x 22/7 x (24 – 5.2)

= 1/2 x 22/7 x (24 – 10)

= 1/2 x 22/7 x 14

= 1/2 x 22 x 2

= 1/2 x 44

= 22

k persegi :

= 2(p+l)

= 2(30+5) + 24

= 2(35) + 24

= 70 + 24

= 94 cm

k total :

22 + 94

= 116 cm (D)
