See attached diagram.
In the first example:
Ratio of sides is 2/1
Ratio of perimeters is 2/1
Ratio of areas is 4/1
In the second example:
Ratio of sides is 3/1
Ratio of perimeters is 3/1
Ratio of areas is 9/1
We can derive these formulas:
Ratio of sides is a/b
Ratio of perimeters is a/b
Ratio of areas is (a/b)²
For #7, just draw the first example's diagram.
You may not need to label all the sides, though.
