HERE , HEIGHT IS 12M BASE IS 5M HYPOTNUSE IS LENGTH OF LADDER BY PYTHAGOROUS THEORUM HYPOTNUSE^2 = BASE^2 + HEIGHT^2 HYPOTNUSE^2 = 5^2 + 12^2 HYP^2 = 25+144 HYP^2 = 169 HYP = UNDER ROOT OF 169 HYPOTNUSE = 13 m

HERE HEIGHT IS 12M

BASE IS 5M

HYPOTNUSE IS LENGTH OF LADDER

BY PYTHAGOROUS THEORUM

HYPOTNUSE^2 = BASE^2 + HEIGHT^2

HYPOTNUSE^2 = 5^2 + 12^2

HYP^2 = 25+144

HYP^2 = 169

HYP = UNDER ROOT OF 169

HYPOTNUSE = 13 M

THEREFORE LENGTH OF LADDER IS 13 M
