What is the percentage of increase in area of a triangle if its sides are doubled?
Answer,
The area will increase by 300%. The area of triangle with double sides will be 4 times area of initial triangle.
See the formula-
Let a,b,c be the lengths of the sides of a triangle. The area is given by:

where p is half the perimeter, or

Now Let a1 = 2a, b1= 2b , c1= 2c be the sides of a triangle then
its area A1 is given by -
