Rectangle ABCD has vertices point A (−5, 1), point B (−2, 1), point C (−2, 6), and point D (−5, 6). Find the perimeter of the rectangle in feet
what's the area
The length of side AB is 2 units (the x-coordinates of A and B are only 2 units apart) and the width of the rectangle is 5 units (the y-coordinates of B and C are 5 units apart). Therefore, the perimeter is:
2 + 5 + 2 + 5 = 14
So the perimeter of the rectangle is 14 feet.
