PLEASE HELP ASAP!!! ILL GIVE BRANLIEST *EXTRA POINTS* !! PLEASE DONT SKIP :(((
mezya [45]

Answer:

92.5 centimeters.

Step-by-step explanation:

The one-meter snake showed up as 2 cm in the developed photo. Since there are 100 centimeters in a meter, you subtract the length of the snake in centimeters by the length it shows up in the picture. 100-2 is 88, so that would be the difference. To find the length of the wall, you add the difference to how it showed up in the picture. 88+4.5=92.5.
