find the perimeter of the squar

length, x+7
width,x+3

The perimeter of a square is found by adding up all four sides.

In this case, the length of the square is given as x+7 and the width is given as x+3.

The perimeter can be calculated as follows:

Perimeter = (x+7) + (x+3) + (x+7) + (x+3)

Simplifying this, we get:

Perimeter = 4x + 20

So the perimeter of the square is 4x + 20.
