Question

BC
4. In adjoining figure, AP
AD || BC, then find
A(A ABC) A(BCD)​

Answer 1

Area of triangle = 1/2 × b × h

ABC and BCD are triangle lying between same parallels and having the same base BC.

A1 :

Area of triangle ABC = 1/2 × BC × AP

A2:

Area of triangle BCD = 1/2 × BC × AP

Now

A1 : A2 = 1 : 1

Answer 2

Answer:

Given:

AP ⊥ BC

AD || BC

∴A(△ABC)/A(△BCD)=AP×BC/AP×BC

=1/1

Hence, the ratio of A(∆ABC) and A(∆BCD) is 1 : 1.
