Use the image to answer the question.
A grid 16 columns by 8 rows shows a trapezoid on it. The top left vertex is at the start of 2nd row and end of 3rd column. The top right vertex is at the start of 2nd row and end of 13th column. The bottom left vertex is at the end of 7th row and end of 1st column. The bottom right vertex is at the end of 7th row and end of 15th column.
A designer wants to estimate the area of a trapezoid-shaped stage. Each square represents one square foot. The designer decides to find the area by composing a rectangle. What is the length of the base of the rectangle in feet?

An illustration shows a parallelogram that is divided into four equal sections by a horizontal and a vertical line intersecting at the center. Measurements are labeled on the bottom first section as follows: The base is labeled 8 inches and left side is 5 inches. The perpendicular height from the top left vertex to the base is 4 inches. The height is drawn in dashed line.

Each paving stone is a parallelogram, with a base of 8 inches and a height of 4 inches. The area of one paving stone is base x height = 8 inches x 4 inches = 32 square inches.
Since there are 4 paving stones in total, the area covered by the 4 paving stones is 4 x 32 = 128 square inches.
Therefore, the correct answer is 128 square inches.
- Area of parallelogram 1 (base of 8 inches, height of 4 inches): 8 inches x 4 inches = 32 square inches
- Area of parallelogram 2 (base of 8 inches, height of 4 inches): 8 inches x 4 inches = 32 square inches
- Area of parallelogram 3 (base of 5 inches, height of 4 inches): 5 inches x 4 inches = 20 square inches
- Area of parallelogram 4 (base of 5 inches, height of 4 inches): 5 inches x 4 inches = 20 square inches
Adding the areas of all four parallelograms together:
32 + 32 + 20 + 20 = 104 square inches
Therefore, the correct answer is 104 square inches. Thank you for pointing out the error.
