Step-by-step explanation:
√52-√13+√117
sqrt (4*13) - sqrt (13) + sqrt (13*9)
sqrt(4)sqrt(13) -sqrt(13)+sqrt(13)sqrt(9)
2sqrt(13) -sqrt(13)+3sqt(13)
sqrt(13)[2-1+3]
4sqrt(13)

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
