Find the length of the side using the distance formula

Length = sqrt((x2-x1)^2 + (y2-y1)^2)

Length = sqrt((2- -1)^2 + (3-4)^2

Length = sqrt(10)

The length of the side is sqrt(10)

A pentagon has 5 equal sides. Multiply the length of the side by 5

Answer: 5sqrt(10)

2.5√10

Answer:

Solution given:

[tex](x_1,y_1)=(-1,4)[/tex]

[tex](x_2,y_2)=(2,3)[/tex]

Now

distance between two end points:

d=[tex]\sqrt{(x_2-x_1)²+(y_2-y_1)²}[/tex]

d=[tex]\sqrt{(2+1)²+(3-4)²}=\sqrt{9+1}=\sqrt{10}[/tex]

we have

perimeter of Pentagon: 5d=5[tex]\sqrt{10}[/tex]
