To find the length of the rectangle, we look at the difference in the x-coordinates of two opposite vertices.
Length = x-coordinate of Point B - x-coordinate of Point A
Length = 5 - 1
Length = 4 miles
To find the width of the rectangle, we look at the difference in the y-coordinates of two opposite vertices.
Width = y-coordinate of Point C - y-coordinate of Point A
Width = -1 - (-3)
Width = 2 miles
Now, we can find the perimeter of the rectangle by adding up all the sides.
Perimeter = 2(Length + Width)
Perimeter = 2(4 + 2)
Perimeter = 2(6)
Perimeter = 12 miles
Therefore, the perimeter of the polygon is 12 miles.
Apply the techniques of using the coordinates to find the length and the width of the polygon. Use the length and the width to find the perimeter of the polygon in miles. Rectangle ABCD has vertices point A (1,−3) , point B (5, −3) , point C (5, −1) , and point D (1, −1) .(1 point)
