Question

A ladder whose foot is 9 metre from the front of a house teaches a window 40 metre above the ground what is the length of the ladder​

Answer 1

Answer:

Length Of Ladder = 41 m

Step-by-step explanation:  

Ladder bottom from ground of House = 9 m

Height Of window = 40 m

to find length of Ladder we will apply Pythagoras theorem

Diagonal² = Length² + Breadth²

(Length of Ladder)² =  40 x 40 + 9 x 9 or 40² + 9²

(Length of Ladder)² = 1600 + 81

(Length of Ladder)² = 1681

Length Of Ladder = 41 m

HOPE IT IS HELPFUL !!!

Answer 2

Answer:

41

Step-by-step explanation:

according to phytagorous theorem:

(hypotenuse)*2=(base)*2+(height)*2

so (hyp)*2=(9)*2+(40)*2

=81+1600

hyp =√1681
