mathstudent55 · Answer

We need top know which side of which trapezoid measures 8 cm.
The information in this problem is incomplete.

mathstudent55 · Answer

My guess is that AD is 8 cm.
I will use my assumption to continue.

hzro · Answer

I will have to ask my teacher.

mathstudent55 · Answer

The trapezoids are on a 2:3 ratio.
Since GH = 6 cm, then 6 cm/3 = 2 cm.
2 cm * 2 = 4 cm.
That means CD is 4 cm
AB is 3 times CD, so AB is 12 cm
My assumption is that AD is 8 cm.
That means that BC is also 8 cm because it is an isosceles trapezoid.

Then because of similar polygons, we can figure out the lengths of the sides of EFGH.
8 cm/2 = 4 cm
4 cm * 3 = 12 cm
6 cm * 3 = 18 cm
