Answer:
50 m
Step-by-step explanation:
We find the perimeter by adding all the sides of our figure.
The initial figure has perimeter :
P = 2 + 5 + 1 + 3 + 3 + 1 + 5
P = 20 m
The dilated figure with the scale factor of 2.5 has perimeter:
P = (2 + 5 + 1 + 3 + 3 + 1 + 5 ) · 2.5
P = 20 * 2.5 = 50 m
Charlie is correct.
