To find the perimeter of a rectangle, we can use this formula:

Where L is the length and W is the width.
We know the perimeter and we know the length and we want to find the width.
Substitute the values back into the formula.
2(35) + 2W = 84
70 + 2W = 84
2W = 14 <-- Subtract both sides by 70
W = 7 <-- Divide both sides by 2
So, width is 7 meters long.
Answer:
The frequency of rolling a 3 or a 6 would be the same even if you try thousands or millions times.
The probability of rolling a 3 is: 1/ total outcomes probability = 1/6
The probability of rolling a 6 is: 1/ total outcomes probability = 1/6
The probability of rolling a 6 or a 3 = 2/ total outcomes probability = 2/6 = 1/3
Therefore, if you rolling the cube 600 times, the probability of rolling a 3 or a 6 is still 1/6. If 3 and 6 are both allowed, the probability would become 1/3

Let x = width of border
Area is given to be 7 square feet or 49.
49 = (2x + 2)(2x + 4)
Solve for x.
