Answer:
Step-by-step explanation:
Well, first of all the shape needs to be a rectangle not a square. And i think you do not understand how coordinates work.
The coordinate (-1, 4). The first number -1 is the number on the x-axis, 4 is the number on the y-axis. Same thing with the other coordinate.
After you put down the two dots, you know that the Perimeter is 24 cm.
P = 2(a + b) = 24 => a+b = 12 => a = 4 => b = 8
The sides are 4 and 8 units long.
