<span>The
number of colors available in a graphic is referred to as color depth. Color
depth is also known as bit depth. It is the number of bits used to indicate the
color of a single pixel, in a bitmapped image or video frame buffer or the
number of bits used for each color component of single pixel.</span>
Answer:
length = float(input("Enter length of the backyard in foot: "))
width = float(input("Enter width of the backyard in foot: "))
sod_price = float(input("Enter the price of sod per square foot: "))
fencing_price = float(input("Enter the price of fencing per foot: "))
area = length * width
perimeter = 2 * (length + width)
cost = sod_price * area + fencing_price * perimeter
print("The cost of landscaping is $" + str(cost))
Explanation:
*The code is in Python.
Ask the user to enter the length, width, sod_price, and fencing_price
Calculate the area and perimeter of the backyard
Calculate the cost, sod_price * area + fencing_price * perimeter
Print the cost
