No worries.
Perimeter = 2x width + 2x height
66 x 2 = 132
338 - 132 = 206
206 / 2 = 103
The length is 103 meters.
Answer:
it would be 8 to 15
Step-by-step explanation:
you would write it as a fraction 8/15. then, you would try and simplify it. because you cant simplify 8/15 anymore, your answer would be 8/15! hope this helps :)
First, pull out a factor of

.

Notice that when

(which you can arrive at via the rational root theorem), you have

which means you can pull out a factor of

. Upon dividing you get

The rational root theorem will come in handy again, suggesting that

appears a second time as a root, which means

Now this is more readily factored without having to resort to the rational root theorem. You have

so in fact,

shows up as a root for a third time.
So, you have

Two roots are obvious,

and

(with multiplicity 3). The remaining two are given by
If you're looking for the area, it is 480 cm squared.
