Question

if perimeter of an equilateral triangle is tripled then find the area of the new Triangle

Answer 1

Because the perimeter is tripled so the side is also tripled.

Hence the area will be 3×3=9 times the area of old triangle

Answer 2

Answer:

If perimeter is tripled then its sides will also be tripled. This means that the scale factor of the enlarged equilateral triangle to the original one is 3. To find the area of the new triangle:

Area=(scale factor)^2*area of the original triangle =9*area of the original

The above states that the area of new triangle will be 9 times as much as the original triangle.
