Area of a Rectangular in a Plane

I am new to programming and I have difficulties with solving a problem. I am coding it in python. May I have some help, please? So the condition says: A rectangular is set on 2 of its opposite angles (x1, x2) and (y1, y2). Find the area and the perimeter of the rectangular. The input is read from the console. The numbers x1, x2, y1, y2 are given one by one on a line.

Inputs and Outputs:

An example:

enter image description here

my code:

x1 = float(raw_input("x1 = "))
y1 = float(raw_input("y1 = "))
x2 = float(raw_input("x2 = "))
y2 = float(raw_input("y2 = "))

if x1 > x2 and y1 < y2:
    a = x1 - x2
    b = y2 - y1
else:
    a = x2 - x1
    b = y1 - y1

area = a * b
perimeter = 2 * (a + b)

print area
print perimeter

You are on the right track!

Let me make a few suggestions:

Inputs

There is nothing wrong with this. (Unless you want to use Python3, where where raw_input is now just input)

x1 = float(raw_input("x1 = "))
y1 = float(raw_input("y1 = "))
x2 = float(raw_input("x2 = "))
y2 = float(raw_input("y2 = "))

Width and Height of the rectangle

If you use the builtin function abs(), you do not have to worry about the sign of (x1 - x2) and (y1 - y2)! Where abs(x) gives the absolute value of x.

width = abs(x1 - x2)
height = abs(y1 - y2)

Area and perimeter

Now that we have the height and width, we can use you code to calculate the area and perimeter:

area = height * width
perimeter = 2 * (height + width)

Bonus

Check if your rectangle is a square:

if height == width:
    print "It's a square!"

Putting everything together:

x1 = float(raw_input("x1 = "))
y1 = float(raw_input("y1 = "))
x2 = float(raw_input("x2 = "))
y2 = float(raw_input("y2 = "))

width = abs(x1 - x2)
height = abs(y1 - y2)

area = height * width
perimeter = 2 * (height + width)

print area
print perimeter

if height == width:
    print "It's a square!"

Let me know if you need me to explain anything!
