4. Shade the rectangle to break it into two smaller rectangles. Then complete the equations to find the total area of the large rectangle. Each \( \square \) represents 1 square unit.

To solve the problem of finding the total area of a large rectangle that has been divided into two smaller rectangles, we can follow these steps: 1. **Identify the dimensions of the large rectangle**: Let's denote the length of the large rectangle as \( L \) and the width as \( W \). 2. **Calculate the area of the large rectangle**: The area \( A \) of a rectangle is calculated using the formula: \[ A = L \times W \] 3. **Break the rectangle into two smaller rectangles**: If the rectangle is divided, we can denote the dimensions of the two smaller rectangles. Let's say the first smaller rectangle has dimensions \( L_1 \) and \( W_1 \), and the second smaller rectangle has dimensions \( L_2 \) and \( W_2 \). 4. **Set up the equations**: The total area of the large rectangle can also be expressed as the sum of the areas of the two smaller rectangles: \[ A = A_1 + A_2 \] where \( A_1 = L_1 \times W_1 \) and \( A_2 = L_2 \times W_2 \). 5. **Complete the equations**: We can express the total area as: \[ A = (L_1 \times W_1) + (L_2 \times W_2) \] Now, if you provide the specific dimensions or any additional information about the rectangles, I can help you calculate the total area more precisely.
