ΔBEF ൽ നിന്ന്,
BF 2 = BE 2 + EF 2, എന്നത് ലഭിക്കും
13 2 = 12 2 + EF 2
⇒ EF 2 = 13 2 - 12 2 = 169 - 144 = 25
EF = 5 സെ.മീ.
ചിത്രത്തിൽ നിന്ന്,
⇒ CD = EF = 5 സെ.മീ, AB = DE = 15 സെ.മീ
CF = CD + DE + EF = 5 + 15 + 5 = 25 സെ.മീ.
ട്രപസോയിഡലിന്റെ വിസ്തീർണ്ണം = ½ × BE × (AB + CF) = ½ × 12 (15 + 25) = 240 ചതുരശ്ര സെ.മീ.
