Konsep Layang - Layang

AD = AB

OD = OB

CD = BC

Panjang Garis AO

AO² = AD² - OD²

AO² = 10² - 8²

AO² = 100 - 64

AO² = 36

AO = √36

<[ AO = 6 cm ]>

Panjang Garis OC

⅖( CO ) = AO

CO = 5/2 × 6 cm

CO = 5 × 3 cm

[ CO = 15 cm ]

Panjang Garis CD / BC

CD² = OD² + CO²

CD² = 8² + 15²

CD² = 64 + 225

CD² = 289

CD = √289

( CD = 17 cm )

Langsung Saja

Keliling Layang - Layang

K = AD + AB + CD + BC

K = 2( AD atau AB ) + 2( BC atau CD )

K = 2( 10 cm ) + 2( 17 cm )

K = 20 cm + 34 cm

{ K = 54 cm } { d. }
