☞︎︎︎ Solution :
↣ Let ABCD be the trapezium :
- AB = 60m
- CD = 77m
- BC = 26m
- AD = 25m
➢ Thus, ABCD is parallelogram:
★ Hence
- AB = DE = 60m
- AD = BE = 25m
- EC = DC - DE
⇒ EC = 77 - 60 = 13m
➢ Now , in triangle BEC
➜ Let the height B from EC = h
- Using Formula :
➢ Area of triangle BEC :
- Using Formula -
➝ On Transposing The Terms :
➢ Area of trapezium :
