def myclick():
    A=int(W.get())*int(H.get())
    label3.configure(text="Area of the Rectangle :" +str(A))

root = Tk(className='Python Examples - Find Area of a Rectangle')
myfont=Font(family='Helvetica', size=15, weight='bold' )

label1 =Label(text="Enter the Width of a Rectangle", width=40,font=myfont, fg='Red')

label3 = Label(text=" ", width=40, font=myfont, fg='Green')

W=Entry(font=myfont, width=4)
H=Entry(font=myfont, width=4)

button = Button(text = 'Click me', font=myfont,command = myclick)

label1.grid(row=0, column=0)
W.grid(row=0, column=1)
label2.grid(row=1, column=0)
H.grid(row=1, column=1)
button.grid(row=2, column=0,columnspan=2)
label3.grid(row=5,column=0)

root.geometry("600x500")

mainloop()
