Question

The top of a ladder of length 15m reaches a window 9 m above the ground . What is the distance between the base of the wall and that of the ladder

Answer 1

Hey there!!

Length of ladder = 15m (hypotenuse)
Height of window = 9m (perpendicular)
base = ?

b^2 = h^2 - p^2
       = 15^2 - 9^2
       =  225 - 81
       = 144
b     = 12 m

Therefore, the distance between the wall and ladder is 12m.

Hope it helps!!

Answer 2

Hey there! ☺☻☺

Given,
Length of ladder = 15 m
Height of ladder = 9 m

We know,
H² = P² + B²
(15)² = 9² + B²
B² = 225 - 81
B² = 144
B = √144
B = 12

Hence, Distance b/w the base of wall is 12 m.
