Identify Shape: Identify the shape of the window to calculate its area; assume it's a rectangle for this example.
Measure Length and Width: Measure the length and width of the window; let's say the window is 4 feet wide and 6 feet tall.
Calculate Area: Calculate the area of the window by multiplying the length by the width: Area=4 feet×6 feet.
Perform Multiplication: Perform the multiplication: Area=24 square feet.
Calculate Cost: Calculate the cost by multiplying the area by the price per square foot: Cost=24 square feet∗$80 per square foot.
