Find the value of MN, so that A(∆ABC) = A(∆LMN).

1.	Find the value of MN, so that A(∆ABC) = A(∆LMN).
Answer» A(∆ABC) = A(∆LMN) \(\therefore\) \(\cfrac12\) x BC x AD = 1 2 x MN x LP \(\therefore\) \(\cfrac12\) x 5 x 8 = \(\cfrac12\) x MN x 4 \(\therefore\) MN = \(\cfrac{5\times8}4\) \(\therefore\) MN = 10 cm

Answer»

A(∆ABC) = A(∆LMN)

\(\therefore\) \(\cfrac12\) x BC x AD = 1 2 x MN x LP

\(\therefore\) \(\cfrac12\) x 5 x 8 = \(\cfrac12\) x MN x 4

\(\therefore\) MN = \(\cfrac{5\times8}4\)

\(\therefore\) MN = 10 cm
