a. AD2 + DH2 = AH2
162 + 122 = AH2
256 + 144 = AH2
AH2 = 400
AH = β400
AH = 20 cm.
b. BA2 + AD2 = BD2
162 + 162 = BD2
256 + 256 = BD2
BD2 = 512
BD = β512
BD = β(162 Γ 2)
BD = 16β 2 cm.
BD2 + DH2 = BH2
(16β2)2 + 122 = BH2
512 + 144 = BH2
BH2 = 656
BH = β656
BH = β(42 Γ 41)
bh = 4β41 cm.
c. Panjang (p) = AC & lebar (l) = CG.
Keliling = 2p + 2l, maka :
AC = BD = 16β2 cm.
2p + 2l
2(16β2) + 2(12)
32β2 + 24
45,25 + 24 = 69,25 cm.
Luas = p Γ l, sehingga :
16β2 Γ 12
192β2 = 271,5 cm2
Semoga membantu.
