Answer 2

Answer:

If the side of a triangle is x units then the area of the equilateral triangle is (√3)a²/4.

If the length of side is quadrupled, the the length becomes 4a.

The area now is (√3)(4a)²/4 = 16 {(√3)a²/4}.

Thus the new area will be 16 times the original area. or area increases to 1600%.
