Answer 2

key point -"use the property of similar triangle"

sabse pehle ABC triangle banao using scale (scale helps me a lot, hope it helps u too).

uske baad M and N daalo scale se hi.

agar problem aa rhi hai ABC banane mein toh aap ek graph lekar points ko mark kar sakte hai. (it helps at initial stage, baad mein aap isme bina graph ke perfect ho jaoge).

ab aap dekho ki Point A common aa rha hai chote aur bade triangle mein, bass property of similar triangle lagae.

usse MN/BC =AM/AB aega

bass ho gya

we know that AB = 2AM (M is midpoint)

so BC = 2 MN

hope it helps
