${\sf{\green{\underline{\large{To\:find}}}}}$

• Increased in Area

Diagram

$\setlength{\unitlength}{5mm}\begin{picture}(5,5)\put(0,0){\line(1,0){8}}\put(0,0){\line(2,1){6}}\put(8,0){\line(-2,3){2}}\end{picture}$

Solving

Let the side of Equilateral ∆ be x

Then

Area of Equilateral ∆ is

$\boxed{\boxed{\sf\red{\dfrac{\sqrt{3}}{4}\times{a^2}}}}$

Area will be

√3/4 × x²

According to the question

• Side of ∆ is doubled

Then new side will be 2x

New Area will be

√3 /4 ×4x²

Increased In area

• Here √3 /4 is a constant no

Therefore

= (4x²-x²)

=3x²

Now increased in percentage

$\tt\implies\dfrac{3x^2}{x^2}\times{100}$

=>300%
