Let Δ be the area of a triangle. Find the area of a triangle whose each side is twice the side of the given triangle.
When each side of triangle = a
When a, b and c are the sides of triangle and s is the semi-perimeter, then its area is given by:
A = where [Heron’s Formula]
A’ = where [Heron’s Formula]
When each side of triangle = 2a
= = 2
A’ = = 4= 4A
