Detailed Solution

Given that, CD||AE and CY||BA .
Question ImageEvaluate, ΔACE and ΔADE are on the same base AE and between the same parallels. CDAE.
We know that the area on the same base and between the same parallels are equal in area. So,
Area (ΔACE)= Area (ΔADE) Area (ΔCEA) Area (ΔAZE)= Area (ΔADE)Ar(ΔAZE)   Area (ΔCZA)= Area (ΔZDE)                             ……(1)
Evaluate, ΔCBY and ΔCAY are on the same base Question Image and between the same parallels. CYBA. Then, area (ΔCBY)= Area (ΔCAY) Add ΔCYG on both sides,
Analyse that,
Area (ΔCBY)+ Area (ΔCYG)= Area (ΔCAY)+ Area (ΔCYG)   Area (BCYZ)= Area (ΔCZA)                          ……(2)
Compare (1) and (2),
Area (BCZY)= Area (ΔEDZ)
Hence, the statement is true.
Therefore, option 1 is correct.
