Question

Triangle ABC is similar to triangle DEF and their perimeters are 32cm and 24cm respectively. If AB = 10 cm, find DE.

Answer 1

Hlo mate :-

Solution :-

________________________________________________________________________________

☆ ∵ ∆ABC ~ ∆DEF

=> Perimeter of ∆ ABC / Perimeter of ∆DEF = AB/DE

=> 32/24 = 10/DE

:- DE = 7.5 cm Ans

Answer 2

$\bf\huge\boxed{\boxed{\boxed{\:Content\:Quality}}}$

$\bf\huge\boxed{\boxed{\:Given}}}$

⇒ ∆ABC ≡ ∆DEF

=> $\bf\huge\frac{Perimeter\:of\:ABC}{Perimeter\:of DE.f}$ = $\bf\huge\frac{AB}{DE}$

=> $\bf\huge\frac{32}{24}$ =  $\bf\huge\frac{10}{DE}$

⇒ DE = 7.5 cm
