Answer 1

$\huge{\pink{\underline{\underline{\sf{✒SoluTion:}}}}}$

Given,

Height of ∆le = 3cm

Area of ∆le = 36cm²

Let's, Base of ∆le = b

✒️$\boxed{\sf{Area\;of\;∆le = \frac{1}{2}×b×h}}$

So,

$→\;{\bf{\frac{1}{2}×b×3 = 36}}$

$→\;{\bf{\frac{1}{2}×b= {\cancel{\frac{36}{3}}}}}$

$→\;{\bf{b = 12×2}}$

$☞\;{\bf{b = 24}}$

.:. The Base of ∆le ◕➜ $\fbox\red{\sf{24cm}}$
