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).
Hi! I've got the answers for the quick check :D
1. 8cm
2. (−6, 4)
3. 12 miles
4. 46 kilometers
5. 32 square feet

Hope I helped~!
To find the length and width of the rectangle, we can use the distance formula between two points:
Length: AB = sqrt((5-1)^2 + (-3-(-3))^2) = 4 miles
Width: BC = sqrt((5-5)^2 + (-1-(-3))^2) = 2 miles
To find the perimeter of the rectangle, we add up the lengths of all four sides:
Perimeter: AB + BC + CD + DA = 4 + 2 + 4 + 2 = 12 miles
