I think the dimensions are 16 ft by 10 ft. Is this right?

**Michael**, Saturday, November 24, 2007 at 11:43amNo. Can you explain what you did to get that?

**keisha**, Saturday, November 24, 2007 at 11:48amI tried to make a proportion 4/6=x/24 and that's how I got 16. Then I got another proprtion 4/6=x/15 and I got 10. What did I do wrong?

**Michael**, Saturday, November 24, 2007 at 11:51amIf you just think about how realistic your answer is, a drawing of those dimensions would be much too difficult to handle. That's a good way to know you've done something wrong.

Start by finding the scale for 1 foot. That should put you in the right direction.

**Michael**, Saturday, November 24, 2007 at 11:54amYou may have used the scale 4 FEET = 6 feet when you should have done 4 INCHES = 6 feet. That's probably what you did wrong.

**Michael**, Saturday, November 24, 2007 at 12:34pmTo get the conversion factor for every foot, convert feet to inches.

4 in = 6 ft

4 in = 72 in

(divide by 4)

1 in = 18 in

For every 18 inches (1.5 ft), your scale will be only 1 inch. You must have done this backwards.

Try your multiplication again to get the final answer.

**keisha**, Saturday, November 24, 2007 at 12:49pmwhat do you have to multiply?

**Michael**, Saturday, November 24, 2007 at 12:54pmYou're not actually multiplying. Sorry.

24 ft by 15 ft

Divide each by 1.5 so that it fits our conversion factor (1.5 ft = 1 in).

24/1.5 = 16 inches

Do the same thing with 15.
