Question

A ladder leans against a vertical wall and reaches to a height of 3.2 m. If the foot of the

ladder is 0.8 m from the wall, calculate the length of the ladder.​

Answer 1

Answer:

THE LENGTH OF THE LADDER IS 3.29 m.

Step-by-step explanation:

HERE SQUARE OF THE LENGTH OF THE LADDER = 3.2²+0.8² = 10.88

THEREFORE THE LENGTH OF LADDER IS √10.88= 3.29.

Answer 2

Height = 3.2m

Distance of ground between ladder and wall

= 0.8m

(Hypotenuse)² = (3.2)² + (0.8)²

[By Pythagorus theorem]

= 10.24 + 0.64

= 10.88

Hypotenuse = √10.88

= 3.2984
