Quinn is determining the area of a trapezoid. His work is shown below. A trapezoid has a base of 14 centimeters, a height of 6 centimeters, and a top side length of 10 centimeters. Step 1: Break the figure into rectangles and triangles. A trapezoid is broken into a rectangle and 2 triangles. The rectangle has a height of 6 centimeters and a base of 10 centimeters. The triangles each have a base of 2 centimeters and a height of 6 centimeters. Step 2: Find the area of the rectangle: 6 times 10 = 60. Step 3: Find the area of the triangles: One-half times 2 times 6 = 6. Step 4: Add the areas together: 60 + 6 = 66 square centimeters. Which best describes Quinn’s error?
