Question

in the figure BD=8,BC=12,B-D-C, then A (∆ABD)/A(ADC)=?​

Answer 1

Answer:

Step-by-step explanation:

To find:

The a(Aabd)/ a(Aadc) =

Solution:

From given, we have,

BD = 8, BC = 12 and B-D-C

Consider the attached figure while going through the following steps.

Construction: Draw a line perpendicular

to the BC from A and mark the point as X.

Now consider,

Area of A ABD,

Ar(A ABD) = 1/2 x BD x AX = 1/2 x 8 x h = 4h

Now consider,

Area of A ADC,

Ar(A ADC) = 1/2 x DC X AX = 1/2 x 4 × h = 2h

Therefore, we have,

Ar(A ABD) / Ar(A ADC) = 4h/2h

:. The value of Ar(A ABD) / Ar(A ADC) =
