If the sides of a triangle are double than the area will be how many times of the original area?

• Consider right angled triangle.
  A1=1/2*b1*h1=b1*h1/2
  b2=2b1 and h2=2h1
  A2=1/2*b2*h2=1/2*2b1*2h1=2b1*h1
  A2=4A1
  Hence,4 times

• Concider equilateral triangles
  hight(h)= a* square root of 3/2
  Area of a equilateral triangle= 1/2*(base*hight)
  (1/2)*a*(a* square root of 3/2)
  so b=2a
  Area of a equilateral triangle= (square root of 3/4)*(2a)^2
  (square root of 3/4)*(4a^2)
  hence, 4 times
