Perimeter is the sum of all sides in the figure. Here, all six sides are equal in length so it would be:
p = 6 * side
p = 6 * 3.9
p = 23.4 cm
In short, Your Answer would be: 23.4 cm
Hope this helps!
Answer:
rational
Step-by-step explanation:
first make two triangles using M , so there iwll be 90-45-45, and 30-60-90 then use the side rules of those special triangles
706,421 rounded to the nearest thousand is 706,000 because the 421 is less than 500 so the 6 would remain a 6.
Simple...
you have:

and

Now, the first one is easy just divide it...

Now....

needs to be converted...
Multiply the whole number*denominator...
4*8=32
Now add the numerator....
32+3=35
Now use the original denominator...

Now divide...

Thus, your answer.
