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?

The length of the base of the rectangle in feet can be calculated by finding the difference between the x-coordinates of the top left and top right vertices of the trapezoid.
End column of top right vertex = 13
End column of top left vertex = 3
Base length = 13 - 3 = 10 feet
Therefore, the length of the base of the rectangle is 10 feet.
