Answer 7

You have the first diagram marked with dimensions, but not the second. Isn't there at least one dimension pertaining to the 2nd? Alternatively, is the first diagram to be enlarged or made smaller? If so, by what factor? For example, should the copy be twice as large as the original? Note that the angles inside the figures will not change if you enlarge or make smaller the diagrams.

Answer 8

heres a screen shot of it, the second one has no sides marked with any length :(

Answer 12

sorry if i mass tagged i just really am confused with this question

Answer 13

please keep in mind that we have this:
\[\huge \frac{{AD}}{{EH}} = \frac{1}{2}\]

Answer 14

thats the ratio, right?

Answer 15

yes!

Answer 16

I reviewed the problem and see that there is a statement saying that the size ratio is 1:2. That means every side in the 2nd figure is 2x as large as its corresponding side in the first. Does that help?

Answer 17

this is equivalent to saying that the 1st figure is half the size of the 2nd figure.

Answer 18

so i multiply side AD by 2?

Answer 19

Side AD is 7m.
Yes, exactly.

Answer 20

so 7 * 2 = 14 and 14 is = EH?

Answer 21

that's right!

Answer 22

Yes.

Answer 23

because i found this question and it states otherwise
