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)

The area of the rectangle within the composite shape can be found by subtracting the area of the triangle from the total area of the composite shape.

Total area = Area of rectangle + Area of triangle
40 = Area of rectangle + 10
Area of rectangle = 40 - 10
Area of rectangle = 30 square inches

So, the area of the rectangle within the composite shape is 30 square inches.
