Question

#Comparing two rectangles

R_1_L = float( input("Please enter the length of Rectangle 1: ") )
R_1_W = float( input("Please enter the weidth of Rectangle 1: ") )
R_2_L = float( input("Please enter the length of Rectangle 2: ") )
R_2_W = float( input("Please enter the weidth of Rectangle 2: ") )

R_1_A = R_1_L * R_1_W
R_2_A = R_2_L * R_2_W

if R_1_A > R_2_A:
print("R 1 is bigger than R 2")

elif R_1_A < R_2_A:
print("R 2 is bigger than R 1")

else:
print("R 1 is equal to R 2")

Please enter the length of Rectangle 1:

54
32
45
98
