Answer 1

Answer:

$\large\color{red}\underline{\underline{Question:}}$

A area of a isosceles triangle is 12 m ² . If one of the equal side is 5 m . Find its base .

$\large\color{orange}\underline{\underline{Given:}}$

$Area\:of\:an\:isosceles\:triangle=12m²$

$Its\:one\:equal\:side\:is=5 m$

$\large\color{purple}\underline{\underline{To\:find:}}$

$Base\:of\:the\:isosceles\:triangle=??$

$\large\color{green}\underline{\underline{Taken:}}$

$Let\:the\:base\:be\:x$

$\frac{Height×Base}{2}=12m²$

$\large\color{blue}\underline{\underline{Solution:}}$

$\Rightarrow{\frac{5m×x}{2}=12m²}$

$\Rightarrow{5×x=12m²×2}$

$\Rightarrow{5x=24m²}$

$\Rightarrow{x=24m²/5}$

$\therefore\boxed{x=4.8m²}$

$\large\color{pink}\underline{\underline{Conclusion:}}$

So , the base of the isosceles triangle is 4.8 m ².
