\(In the figure shown, the ratio of $BD$ to $DC$ is $4$ to $3$. The area of $\triangle ABD$ is $24$ square centimeters. What is the area of $\triangle ADC$? \)

Hi Shreyas1,


You most likely would have had an answer much more quickly if your question was presented in a readable fashion!

But here is your answer  smiley


\(\frac{BD}{DC}=\frac{4}{3}\\ \text{so let BD=4x and DC=3x }\\ Area\;\;\triangle ABD=0.5*4x*h=24\\ \qquad \qquad 2xh=24\\ \qquad \qquad xh=12\\~\\ Area\;\;\triangle ABC=0.5*7x*h\\ Area\;\;\triangle ABC=3.5xh\\ Area\;\;\triangle ABC=3.5*12\\ Area\;\;\triangle ABC=42cm^2\\\)


NOW do the subtraction to get the final answer :)

Hey melody,

how are you. Thank you for answering my question. Also sorry about the question, I will try to not do that again. And by subtracting you get 18 right :)
