20 in²
Step-by-step explanation:
Area of the shaded portion = Area of the bigger square - Area of the middle sqare + Area smaller square
Area of the bigger square = 5 in × 5 in
Area of the bigger square = 25 in²
Area of the middle square = 3 in × 3 in
Area of the middle square = 9 in²
Area of the smaller square = 2 in × 2 in
Area of the smaller square = 4 in²
Area of the shaded portion = 25 in² - 9 in² + 4 in²
Area of the shaded portion = 20 in²
