To find the total area of the shape formed by the three rectangles, you need to sum the areas of all three rectangles.
Given:
- Area of Rectangle 1 = 90 cm²
- Area of Rectangle 2 = 54 cm²
- Area of Rectangle 3 = 54 cm²
Now, let's calculate the total area:
\[ \text{Total Area} = \text{Area of Rectangle 1} + \text{Area of Rectangle 2} + \text{Area of Rectangle 3} \]
\[ \text{Total Area} = 90 , \text{cm}^2 + 54 , \text{cm}^2 + 54 , \text{cm}^2 \]
\[ \text{Total Area} = 90 + 54 + 54 = 198 , \text{cm}^2 \]
Therefore, the total area of the shape is 198 cm².
