Question

IN ∆ ABC point D is on side BC such that BD=3 BC =5 find A(∆ABD)/A(∆ABC)​

Answer 1

Answer:

I give you a hint you slove that question

Answer 2

Answer:

3/5

Step-by-step explanation:

Given : point D is on side BC such that BD=3 BC =5

To find : A(∆ABD)/A(∆ABC)

Solution:

Let draw AM ⊥ BC

As D is a point on BC

Hence AM ⊥ BD also

Area of Δ = (1/2) * Base * Height

Area of Δ ABC = (1/2) * BC * AM

Area of Δ ABD = (1/2) * BD * AM

Area of Δ ABD / Area of Δ ABC = ((1/2) * BD * AM) / ( (1/2) * BC * AM)

=> Area of Δ ABD / Area of Δ ABC = BD/BC

=> Area of Δ ABD / Area of Δ ABC = 3/5

A(∆ABD)/A(∆ABC) = 3/5

I hope this helps ✌️
