The composite shape in the image has an area of 40 square inches. What is the area of the rectangle within the composite shape?
(1 point)
• 16 square inches
• 34 square inches
• 7 square inches
• 28 square inches
The area of the rectangle within the composite shape can be found by subtracting the area of the triangle from the total area of 40 square inches.
Total area = 40 square inches
Area of the triangle = (1/2) * base * height = (1/2) * 8 * 5 = 20 square inches
Area of the rectangle = Total area - Area of triangle = 40 - 20 = 20 square inches
Therefore, the area of the rectangle within the composite shape is 20 square inches. None of the provided options match this answer, so there might be an error in the question or the options provided.
