Layla is determining the area of the trapezoid. Her work is shown below.

A trapezoid has a base of 14 feet, height of 10 feet, and top side length of 8 feet.

Step 1: Break the figure into rectangles and triangles.

A trapezoid is broken into a triangle and rectangle. The rectangle has a base of 10 feet and a height of 8 feet. The triangle has a base of 10 feet and a height of 6 feet.

Step 2: Find the area of the rectangle: 8 times 10 = 80.

Step 3: Find the area of the triangle: One-half times 6 times 8 = 24.

Step 4: Add the areas together: 80 + 24 = 104 square feet.

Which best describes Layla’s error?
The height of the triangle in Step 1 should be 4 ft.
The area of the triangle in Step 3 should be One-half times 6 times 10 = 30.
The area of the triangle is Step 3 should be halved because there is only one triangle.
The areas in Step 4 should be multiplied instead of added.
