If each side of a triangle is doubled, then the height doubles as well.
Let A be it's initial area.
New area =1/2 *2b *2h, which is 4 times the initial area of the triangle.
Therefore increase in area = 4A - A = 3A
Percentage increase
= 3A/A*100
= 300%
Hope it helps :)

supposed triangle be equilateral triangle
with side=x

now when side became double then area will be=

now,
subtact A2 by A1
then we get SE as given below

now find its percentage
percentage =A3/(A1+A2) ×100
