प्रश्न
In the following figure, OAB is a triangle and AB || DC.
If the area of ∆ CAD = 140 cm2 and the area of ∆ ODC = 172 cm2,
find : (i) the area of ∆ DBC
(ii) the area of ∆ OAC
(iii) the area of ∆ ODB.
उत्तर
Given:
ΔCAD = 140 cm2
ΔODC = 172 cm2
AB || CD
As Triangle DBC and ΔCAD have same base CD and between the same parallel lines,
Hence,
Area of ΔDBC = Area of ΔCAD = 140 cm2
Area of ΔOAC = Area of ΔCAD + Area of ΔODC
= 140 cm2 + 172 cm2 = 312 cm2
Area of ΔODB = Area of ΔDBC + Area of ΔODC
= 140 cm2 + 172 cm2 = 312 cm2.
