Answer:
Step-by-step explanation:
ΔABC, ΔABD, ΔADC all have same height 'h'.
Base length of ΔABC = 15
Base length of ΔABD = 9
Base length of ΔADC = 6
Area of ΔABC= 1/2 × h ×15
Area of ΔABD= 1/2 × h ×9
Area of ΔADC= 1/2 × h ×6
A(ΔABD) : A(ΔABC) = (1/2 × h ×9):(1/2 × h ×15) = 3:5
A(ΔABD) : A(ΔADC) = (1/2 × h ×9):(1/2 × h ×6) = 3:2
