Answer:
The perimeter of rectangle ABCD = 16 units
Step-by-step explanation:
The vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).
AB is horizontal, so measre the difference between the x coordinates of A and B.
between -2 and 3 are 5 units.
BC is vertical, so measre the difference between the y coordinates of B and C.
between 4 and 1 is 3 units.
The perimeter = 2 * ( AB + BC )
Substitute AB = 5 and CD = 3
2 * ( 5 + 3 )
2 * 8
The perimeter of rectangle ABCD = 16 units
