Answer:
6
Step-by-step explanation:
Look at both trapezoids and you can find the relation between both
Line DC and GH are equal, those different measurements they have the same characteristics. Same with AB and FE
Divide GH by DZ and you get the scale that you can apply to find FE
30/7.5 = 4
So line FE is 4 times smaller than AB
24/4 = 6
