To calculate the area of the shaded region within a rectangle, you first need to determine the total area of the rectangle and then subtract the area of any unshaded regions.
The formula for the area of a rectangle is given by:
Area = length × width
Assuming you know the length and width of the rectangle, you can plug in those values to find the total area.
Next, identify the dimensions of the unshaded region, if applicable. This part could also be a rectangle or any other shape. Calculate its area using the same formula.
Finally, subtract the area of the unshaded region from the total area of the rectangle:
Area of Shaded Region = Total Area of Rectangle – Area of Unshaded Region
This will give you the area of the shaded region. Make sure to keep track of the units you are using throughout the calculations!
