The answer to your problem is that Marisol’s shadow would be 144 feet long
Area of trapezoid = Average length of parallel lines x height
3+22=25
25/2= 12.5
12.5x6=75cm^2
Break the figure into a triangle and a rectangle.
The triangle has a base of 6 and a height of 3, so the area is 6*3/2 = 18/2 = 9
The rectangle has a length of 5 and a height of 6, so 6*5 = 30 is the area of the rectangle.
The total area is 30+9 = 39
Answer: 39
