That's not what I got

Oh.

What did you get,then?

Answer 7

That's not what you were supposed to do.

Answer 8

Oh.

Answer 9

Would you show me the procedure,then?

Answer 10

The procedure is to solve proportions:

\[\frac{.25}{3.5} = \frac{1}{x}\]

and

\[\frac{.25}{5} = \frac{1}{x}\]

Answer 11

oh, you do them separately.

Answer 12

After solving both those correctly for x, then you will have the dimensions in feet. Multiply them together.

Answer 13

You don't have to do them separately. You can multiply together, but you can't forget to convert afterwards.

Answer 14

Whatever you get, you multiply that together? both x's?
