<span>To minimize the perimeter you should always have a square.
sqrt(289) = 17
The dimensions should be 17 X 17
To see , try starting at length 1, and gradually increase the length.
The height decreases at a faster rate than the length increases, up until you reach a square.
Or if you want to use algebra, Say the width is 17-x
Then the length is 289/(17-x)
Now, this is bigger than 17+x, as shown here:
289/(17-x) > 17+x
289 > 289 - x^2
which is true.
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17
Again, the dimensions should be a square. 17 X 17.</span>
Answer:
b
Step-by-step explanation:
<span> $947.50
</span> - $189.50
_________
$758.00
So, to do this first we start at the far right and go to the left.
$947.50 - $189.50_________
$ .00
0-0= 0
5-5= 0
You then bring down the decimal.
$947.50 - $189.50_________
$ 8 .00
Because you cannot subtract 9 from 7, you borrow one from the number to the left of it and 7 turns into a 17 as 4 turns into a 3. So then, 17-9=8.
17
$93-7-.50 -7- = This means the 7 has been canceled out and turned - $189.50 into the 17 above _________ 8 .00
This happens again with subtracting 3 from 8 in which you take one from the number beside which happens to be 9 and make it 8.
17
$8-3--7-.50 -7- and -3- = This means the 7 has been canceled out and turned into the 17 above
- $189.50 _________ $ 58 .00
So then, 13-8=5. Finally 8-1= 7
$947.50
- $189.50
_________
$758.00
