you can find the area of this trapezoid by copying it and forming a parallelogram. which shows the trapezoid…

Explanation:

Step1: Recall trapezoid - parallelogram transformation

To form a parallelogram from a trapezoid, we place a copy of the trapezoid adjacent to it such that the non - parallel sides are adjacent to each other.

Step2: Analyze the given trapezoid

The trapezoid has parallel sides of lengths 5 mi and 7 mi and height 4 mi. When we combine two identical trapezoids to form a parallelogram, the base of the parallelogram is the sum of the lengths of the parallel sides of the trapezoid ($5 + 7=12$ mi) and the height remains the same (4 mi). The correct way is to place the trapezoids side - by - side horizontally.
