Answer 1

Jawaban:

AB = 10 cm

BC = 10 cm

CD = 10 cm

AG = 1/2 × AB = 1/2 × 10 cm = 5 cm

BE = 1/2 × BC = 1/2 × 10 cm = 5 cm

EC = 1/2 × BC = 1/2 × 10 cm = 5 cm

CF = 1/2 × CD = 1/2 × 10 cm = 5 cm

DF = 1/2 × CD = 1/2 × 10 cm = 5 cm

AE^2 = AB^2 + BE^2

AE^2 = 10^2 + 5^2

AE^2 = 100 + 25

AE^2 = 125

AE = V125

AE = V(25 × 5)

AE = V25 × V5

AE = 5 × V5

AE = 5V5 cm

EF^2 = EC^2 + CF^2

EF^2 = 5^2 + 5^2

EF^2 = 25 + 25

EF^2 = 50

EF = V50

EF = V(25 × 2)

EF = V25 × V2

EF = 5 × V2

EF = 5V2 cm

DG = AE = 5V5 cm

Luas segitiga ADG

= 1/2 × AG × AD

= 1/2 × 5 × 10

= 25 cm^2

Luas segitiga :

1/2 × AG × AD = 1/2 × DG × AH

1/2 × 5 × 10 = 1/2 × 5V5 × AH

1/2 × 50 = 1/2 × 5V5 × AH (1/2 dicoret)

50 = 5V5 × AH

AH = 50 : 5V5

AH = 2V5 cm
