Jawaban:

•] mencari AB

AB² = AC² – BC²

AB² = 13² – 5²

AB² = 169 – 25

AB² = 144

AB = √144 = 12cm

•] keliling bangun ABCD

K = 2p + 2l

K = 2(12) + 2(5)

K = 24 + 10

K = 34cm

  • Panjang AB

 tt = sqrt{ {13}^{2} - {5}^{2} }

 tt = sqrt{169 - 25}

 tt = sqrt{144}

= 12 cm

  • Keliling

= 2(p + l)

= 2(12 + 5) cm

= 2(17) cm

= 34 cm
