tolong bantu ya karena bsok dikumpulkan

AE = AC - EC
AE = 15 - 5
AE = 10 cm

DE = √AE²-AD²
DE = √100-36
DE = √64
DE = 8 cm

BE = √CE²-BC²
BE = √5²-3²
BE = √25-9
BE = √16
BE = 4 cm

BD = BE + ED
BD = 4 + 8
BD = 12 cm

AB = √12²+6²
AB = √144+36
AB = √180
AB = √36.5
AB = 6√5

Maaf kalau salah, semoga membantu^o^
