Kakak, tolong bantu jawab yaaa, jangan lupa pakai caranya. Terima kasih ☺️

ac= 20
ad= 25
jadi ae= 24
keliling 7+15+12+16+24= 7+27+40=74

AC = √16²+12²
triple phytagoras = 3,4,5 = 12,16,20
AC = 20 cm

AD = √15²+20²
triple phytagoras = 3,4,5 = 15,20,25
AD = 25 cm

AE = √25²-7²
AE = √625 - 49
AE = √ 576
AE = 24 cm



keliling= 16 + 12 + 15 + 7 + 24
keliling = 74 cm
