To find the total area of the three rectangles, you simply add the areas together:
- Area of Rectangle 1: 40 cm²
- Area of Rectangle 2: 24 cm²
- Area of Rectangle 3: 24 cm²
Now, perform the addition:
\[ \text{Total Area} = 40 , \text{cm}² + 24 , \text{cm}² + 24 , \text{cm}² \]
Calculating this gives:
\[ \text{Total Area} = 40 + 24 + 24 = 88 , \text{cm}² \]
So, the total area of the shape is 88 cm².
