We have two squares. The ratio of the perimeter of the big square to the perimeter of the little square is 5 : 2. What is the ratio of the area of the big square to the area of the little square?
I don't know where to start
I have feeling you have to split the ratio into fourths then I'm not sure where to go from there
If the ratio of the perimeter of the squares is 5:2
Then .. What is the ratio of the sides of the squares. Draw a pick and think about it. I'll continue after you answer.
5:2 is the same as 20:8 Do you see why?
20:8 is easier to work with.
Let the squares have a perimeter of 20 and 8 respecively. How long are the sides.?
so you would split 20 and 8 into fourths? I am confused
