Answer:
A. 6m and 2m
E. 11.25m and 3.75m
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional
so
Verify each case
case A) 6m and 2m
therefore
The legs are proportional
case B) 8m and 5m
therefore
The legs are not proportional
case C) 7m and 3.5m
therefore
The legs are not proportional
case D) 10m and 2.5m
therefore
The legs are not proportional
case E) 11.25m and 3.75m
therefore
The legs are proportional
