Answer: 5cm

Step-by-step explanation: The distance of the foot of the ladder from the base of the wall =5 m

Verified answer

Solve with pythagorean theorem

c^2=a^2+b^2

c-measure of the laddee

b-measure of the vertical wall from the top of the ladder to the ground

a-distance of the foot of the ladder to the bottom of the wall.

c=13m

b=12m

a=?

c^2=a^2+b^2

13^2=a^2+12^2

13^2-12^2=a^2

169-144=a^2

√25=√a^2

5 m=a----- final answer Sorry I was solving this for 2 hours...when i saw this question but thats your answer have a nice day!!
