Math Problem Statement

Find the area of the piecewise rectangular figure. Sides meet at right angles.

Solution

To find the area of the given figure, we break the complex shape into two rectangles and calculate their areas separately.

Step-by-Step Breakdown:

  1. Label the two rectangles:

    • Top rectangle has dimensions:
      • Height = 4cm4 \, \text{cm}
      • Width = 6cm6 \, \text{cm} (since 2cm+2cm+2cm=6cm2 \, \text{cm} + 2 \, \text{cm} + 2 \, \text{cm} = 6 \, \text{cm}).
    • Bottom rectangle has dimensions:
      • Height = 5cm5 \, \text{cm}
      • Width = 3cm3 \, \text{cm}.
  2. Calculate the area of each rectangle:

    • Area of top rectangle: Area=Height×Width=4cm×6cm=24cm2\text{Area} = \text{Height} \times \text{Width} = 4 \, \text{cm} \times 6 \, \text{cm} = 24 \, \text{cm}^2
    • Area of bottom rectangle: Area=Height×Width=5cm×3cm=15cm2\text{Area} = \text{Height} \times \text{Width} = 5 \, \text{cm} \times 3 \, \text{cm} = 15 \, \text{cm}^2
  3. Add the areas together: Total Area=24cm2+15cm2=39cm2\text{Total Area} = 24 \, \text{cm}^2 + 15 \, \text{cm}^2 = 39 \, \text{cm}^2

Final Answer:

The area of the figure is 39 cm².
