can someone help me with this? Thank you!

Answer:
10.
Step-by-step explanation:
As the 2 Figures are similar the correspond sides are in the same ratio.
We see that BC = 5.0 and FG = 2.5, so each side in EFGH is 1/2 of its correspond side in ABCD.
Perimeter of EFGH , therefore, is
2.5 + 2 + 4 + 1.5
= 10.
