Ineed this for tm5/3/16

i need on number me, i don't understand

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.

It creates dogx^2 and then flip your answer and multiply by 2
