Question
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?

I apologize for the mistake. Let's reevaluate the problem.
From the description, we can see that the trapezoid has a base of 12 units (from the 3rd column to the 13th column). Each square represents one square foot.
Therefore, the length of the base of the trapezoid-shaped stage is 12 feet. Thank you for your patience.
To find the length of the base of the rectangle, we need to look at the bottom side of the trapezoid.
Counting the number of columns between the bottom left vertex (end of 1st column) and the bottom right vertex (end of 15th column), we get 15 - 1 = 14 columns.
Since each square represents one square foot, the length of the base of the rectangle is 14 feet.
