11. Tentukan keliling gambar tersebut.​

Jawaban:

108 cm

Penjelasan dengan langkah-langkah:

Keliling = Jumlah semua sisi

= 24 + 24 + 24 + 10 + c

c² = a² + b²

= 24² + 10²

= 576 + 100

= 676

c = √676

= 26 cm

Keliling = 24 + 24 + 24 + 10 + 26

= 48 + 24 + 10 + 26

= 72 + 10 + 26

= 82 + 26

= 108 cm
