If the top of a 4.50 m ladder reaches twice as far up a vertical wall as the foot of the
STALIN [3.7K]

Answer:

4 m.

Step-by-step explanation:

Length of ladder, L = 4.50 m

Base of ladder from the wall, B = x

Height of the wall, H = 2x

Using Pythagoras theorem

L^2 = B^2 + H^2

4.5^2 = x^2 + (2x)^2

5x^2 = 4.5^2

x = 2\ m\ (approx.)

Height of the wall  is equal to 2 x 2 = 4 m.
