#problem 1 from Lab 3

#Input:  width, length, radius - float
#Output: area, perimeter, areaCircle

#Part I: Input
#all input data will be float type

width=float(input("enter width "))
length=float(input("enter length "))
radius =float(input("enter radius "))

#Part II: Calculations:

area=width*length
perimeter=2*length+2*width
areaCircle=3.14*radius*radius

#Part III: Output
print("area=", area)
print("perimeter=", perimeter)
print("areaCircle=", areaCircle)
