Answer:
18 meters
Step-by-step explanation:
"Perimeter" is all 4 sides added together, right?
Since it's a square, all four sides are equal, so the problem looks like this:
s + s + s + s = 72 where s = side length
Before doing any math, can you think of a number that you could add to itself 4 times and get 72? If not, you get to do some algebra:
s + s + s + s = 72 reduces to:
4s = 72 Then solve for s:
s = 72/4 = 18 m
Check your work by seeing if 4 x 18 = 72. It does, so the answer is correct.

Answer:
The answer is .
Step-by-step explanation:
When you're rounding up to the "Nearest" all you have to do is find for the thousands place then look to the right of the number. If it's 4 or down, round down. but If it's 5 or up, round up. It's as simple as that. The number to the right of the thousands is 9, so we round up 700,000.
And that will be you're answer!
