Question

If∆LMN~∆DEF,A(∆LMN)=32,A(∆DEF)=98 then LM:DE=..................

Answer 1

Step-by-step explanation:

$\frac{a \: of \: (triangle \: lmn)}{a \: of \: (triangle \: def)} = \frac{lm}{de}$

$\frac{32}{98 } = \frac{lm}{de}$

now,32×de=98×lm

$\frac{de}{lm} = \frac{32}{98}$

we put signs in formula.
