Question

in the given figure find BC if the area of triangle is 36 cm square

please answer fast it's urgent ​

Answer 1

$\huge{\green{\underline{\underline{\bf{\diamond\;Solution:}}}}}$

Given,

• ABD is a ∆le

• AC is the altitude drawn perpendicular to BD

• & BC = CD

☞ Length of AC = 13cm

☞ Area of Triangle = 36 cm²

Let, BC = CD = 'x', Then, BD = '2x'

We Know That

$\boxed{\sf{Area\;of\;∆le = \frac{1}{2}×Base×Height}}$

Base = 2x

$→\;{\bf{\frac{1}{\cancel{2}}×13×{\cancel{2}}x = 36}}$

$→\;{\bf{13× x = 36}}$

$→\;{\bf{x = \cancel{\frac{36}{13}}}}$

$→\;{\bf{x = 2.76}}$

Therefore, Length of BC ◕➜ $\fbox\red{2.76cm}$
