Answer:
To find the area of the shaded region, we need to determine the difference between the area of rectangle ABCD and the combined areas of the smaller squares.
Let's first calculate the area of rectangle ABCD. Given that its area is 1 square unit, we can assign the length of side AB as "a" and the width of side BC as "b". Therefore, the area of rectangle ABCD is equal to a * b.
Next, we need to calculate the combined areas of the smaller squares. Since all the small squares are equal in area, we can assign the length of their sides as "x". The number of small squares can be determined by dividing the length of side AB by the length of side x.
Now, we can express the area of the shaded region as the difference between the area of rectangle ABCD and the combined areas of the smaller squares:
Area of shaded region = Area of rectangle ABCD - (Number of small squares * Area of each small square)
Using the variables we assigned earlier, we can write the expression for the area of the shaded region as:
Area of shaded region = a * b - (a/x * b/x * x^2)
Simplifying this expression further may depend on the specific values of a, b, and x provided in the figure. However, the above expression represents the general formula for calculating the area of the shaded region based on the given information.
