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)
