To find the total area of the shape, you simply add the areas of the individual rectangles together.
- Area of Rectangle 1: 112 cm²
- Area of Rectangle 2: 49 cm²
- Area of Rectangle 3: 64 cm²
Now, calculate the total area:
\[ \text{Total Area} = 112 , \text{cm}² + 49 , \text{cm}² + 64 , \text{cm}² \]
\[ \text{Total Area} = 112 + 49 + 64 = 225 , \text{cm}² \]
So, the total area of the shape is 225 cm².
