Answer 1

Step-by-step explanation:

So, we get a right angled triangle in this situation. Thus, we will apply Pythagoras Theorem here. So, the distance between the foot of the ladder and the wall is equal to 7 cm

Answer 2

Answer:

7m

Step-by-step explanation:

length of wall= 24m

length of ladder= 25m

H^2=b^2+ h^2

25^2= b^2 + 24^2

b^2= 25^2 - 24^2

b^2= 625 - 576

b^2= 49

b= 7
