If ←→AD||←→BC, then area (ΔABC) = area (ΔBEC). = area (ΔDBC)
In the given, ABCD is a quadrilateral with diagonals AC and BD intersecting at point O. Hence, area of Δ AOD × area of Δ BOC = area of Δ AOB × area of Δ COD.
Question 102
ABCD is a parallelogram in which AE is perpendicular to CD is shown in the given figure. Also, AC = 5 cm, DE = 4 cm and area of ΔAED=6 cm2. Find the perimeter and area of parallelogram ABCD.
If ←→AD||←→BC, then area (ΔABC) = area (ΔBEC). = area (ΔDBC) State true or false
