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? (1 Point)
To find the length of the base of the rectangle, we need to add the lengths of the two parallel sides of the trapezoid.
Let's assume the trapezoid-shaped stage is in the form of a trapezoid ABCD where AB and CD are the parallel sides, and AD and BC are the non-parallel sides.
If we consider the rectangle that can be composed, it would have the same width as the trapezoid and a length equal to the sum of the lengths of the parallel sides of the trapezoid.
Therefore, the length of the base of the rectangle would be AB + CD.
