Area of triangle 1 = 16

Area of triangle 2 = 9

Since area is the only one given I suppose that the triangle is an equilateral

get the sides of T1

16x4=64/square root of 3=36.95 then square the answer give you 6.08

get the sides of T2

9x4=36/square root of 3=20.78 then square the answer give you 4.56

Now get the ration T1:T2

6:5 ^^
