Answer:
8.625 ft for each side.
Step-by-step explanation:
This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).
Let the unknown number be x. Then (1/10)x = 0.002. To solve for x, multiply both sides by 1000 to remove the decimal fraction 0.002.
Then 1000(1/10)x = 1000(0.002), or 100x = 2. Dividing both sides by x returns
x=100/2, or x= 50 (answer)
