Step-by-step explanation:
First, find the area of the rectangle:
In order to find the area of the shaded region, we can subtract the areas of the two sectors from the total area of the rectangle.
Find the area of the sectors. We can use the sector formula:
The left sector has a radius of three units and an angle of 90°. Hence, its area is:
The right sector is identical to the left sector. So, the total area of the two sectors is:
Hence, the area of the shaded region is:
