Answer:

1:1:1

i hope it helps you

Answer 2

Answer:

4:1

Step-by-step explanation:

solution

i) Let side of an equilateral triangle= a

area of the triangle=(squareroot3/4)a²----(1)

ii)if side is doubled

side of new equilateral triangle= 2a

area of new triangle=(squareroot3/4)×(2a²)-----(2)

ii) required ratio=(2)/(1)

=[(squareroot3/4)×4a²]/[(squareroot3/4)×a²]

After cancellation,we get

=4:1
