AE = √(15²-12²)
= √225 – 144
= √81
= 9 cm
∆AFD = tripel phytagoras = 6, 8, 10
sehingga DE = 10 – AE
= 10 – 9 = 1 cm
AD = AE + DE = 10 cm
Kel. = 15 + 15 + 10 + 10
= 50 cm —-> C

AB = √(12²+9²)
= √144 + 81
= √225
= 15 cm
BC = √(16²+12²)
= √256 + 144
= √400
= 20 cm
kel. = 15 + 15 + 20 + 20
= 70 cm —-> C
