What is the ratio of the area of triangle XBY to the area of triangle ABC for the given measurements, if XY is similar to AC?
the ratio of area is proportional to the square of the sides
which would be 3^2/2^2 = 9/4
or as a ratio 9 : 4
i don't seem to understand the concept
Area1/Area2 = (side1)^2/(side2)^2
so 4/9 ?
yes, I had 9/4 since you gave your sides as 3 and 2
Obviously the bigger area goes with the bigger side.
I am sure you can now do the others that are similar to this
