Answer:
I think the legnth is 15 ft
Explanation:
If you measure the bottom side of the trapezoid ABCD it tells you that it is 7 feet and the sides of GHIJ are 4.5 feet and you need to go around the trapezoid.
The answer is 15 ft.
since the trapezoids are similar, they have a scale factor of 3 because 4.5 divided by 3 is 1.5, so 5 x 3 is 15 ft.
