The perimeter of square RSTV is: 17.88 units
Further explanation:
As the given figure is a square, all of its sides will be equal. So we have to find one side to find the perimeter.
Given
R(-1,5), S(-3,1), T(-7,3), and V(-5,7)
The distance formula will be used to find the side

Let x be one side of square

Let P be the perimeter of square
P= 4x
P=4*4.47
=17.88 units
The perimeter of square RSTV is: 17.88 units
