Question

MEDAL for help:

Answer 1

These two shapes are similar; therefore, that means that there's a ratio relating them.

What we're looking for is a given relationship between two like sides

Answer 2

right i get that.

Answer 3

so which two like sides are we given values for?

Answer 4

AD and FG

Answer 5

yep!

so the way you find the ratio is like this:

3:18
^
but we can simplify this, can't we? what is 18 divided by 3?

Answer 6

6

Answer 7

mhm. so basically, to make the bigger triangle, you multiply that side by 6.

Since you're given that the larger side on the smaller rectangle is 5, and the ratio is 1:6, you would multiply 5 by 6. And that will give you the side of the larger rectangle

Does that make sense?

Answer 8

5*6=30

Answer 9

yes, so D is my answer

Answer 10
