Question

AD is a median triangle ABC. Area of triangle ADC is 15cm square. then area(triangle ABC)

Answer 1

median divides triangle into two triangles of equal areas

area of ADC=area of ABD

area of ADC+area of ABD

=15+15

area of ABC is 30cm sq

hope this helps you

pls mark me as brainliest for answering the first

Answer 2

Area(triangle ABC) is 30 cm square.

Step-by-step explanation:

Given:

We have ABC as the triangle in which AD is median to BC.

We know that median of a triangle divides it into 2 triangles of equal areas.

So, ar(ΔADC) = ar(ΔADB)

⇒ $ar(\triangle ADC) = ar(\triangle ADB) = 15 cm^2$    [given]

Now, ar(ΔABC) =  ar(ΔADC) + ar(ΔADB)

= 15 + 15

= $30 cm^2$
