→ Hey Mate,
→ Given Question :
. A ladder is resting against a wall. The top of the ladder touches the wall at height of 12 m. Find the length of the ladder if the length is 6 m more than its distance from the wall.
→ To find :
. Find the lenght of the ladder = ?
→ Given :
. Lenght = 6 m
. Height = 12m
→ solution:
⇒ Let Distance from wall be m.
⇒ Length , L = x + 6
⇒( x + 6 ) ² = 12² + x²
⇒ x² + 12x + 36 - 144 -x² = 0
⇒ 12x - 108 = 0
⇒ 12x = 108
⇒ 12x = 108
⇒ x =
⇒ 9
⇒ Length = 9 + 6 = 15
⇒ Ans : length = 15m
⇒ Final Answer : 15m
