Answer:

10.

Explanation:

As the figures are similar corresponding sides ( including the perimetrers) are in the same ratio, so:

2.5/5 = P/20 where P is the perimeter of EFGH.

5P = 20*2.5

P = (20*2.5)/5

= 50/5

= 10.

Answer:

10

Explanation:

The lines B-C and F-G show us the scale factor is 1/2. Therefore, you halve all the values of FGEH to get: 2.5+2+4+1.5=10, or half of the original shapes perimeter, 20.
