Answer:
100 i think if its a square its 100
Step-by-step explanation:
The first thing you do is subtract 2 from both sides to move the 2 to the left side
3-6x=7x
now add 6x to both sides to move -6x to the right
3=13x
divide by 13 to eliminate the 13 on the right side
3/13
−129=−48−n
Simplify:
−129=−48+−n
Flip the equation.
−n−48=−129
Add 48 to both sides.
−n−48+48=−129+48
−n=−81
Divide both sides by -1.
−n/−1 = −81/−1
n=81
To solve this problem you must apply the proccedure shown below:
1. The formula for calculate the perimeter of a rectangle is:
Where 
is the length and 
is the width.
2. The length is 
more than the width, therefore:
3. Substitute values into the formula for calculate the perimeter and solve for the width:
3. Then, the length is:
The answer is: The length is 
and the width is
