A 20-foot extension ladder can typically reach a height of about 18 to 19 feet when fully extended, depending on the angle at which it is positioned and the height of the person using it. The ladder's top rung is not meant to be stood on for safety reasons, so the effective working height is slightly less than the total length. Always follow safety guidelines to ensure stability and proper usage.

When a painter leans a 29 foot ladder so that the base of the ladder is 21 feet from the wall. What is the height at which the top of the ladder touches the wall?
Using Pythagoras' theorem it is 20 feet
How long must a ladder be to reach the top of a 20' wall if the ladder and the wall form a 32 degree angle at the top?
Then an angle of 58 degrees will be at the bottom of the ladder. Use trigonometry and the sine ratio: sin = opp/hyp and hyp = opp/sin hyp = 20/sin(58) = 23.58356807 length of ladder = 24 feet to the nearest foot
A painter is painting a mural on a wall. He has a 20-foot ladder. He needs to work on a part of the wall that is 16 feet above the ground. How far from the base of the building should he place the foo?
Using Pythagoras' theorem the the foot of the ladder should be 12 feet away from the base of the building.
How long must a ladder be to reach to top of a 20 foot wall if the ladder and the top wall form a 32 degree angle at the top in a plus?
The ladder forms the hypotenuse (r) and the wall forms the vertical (y) of a right triangle. sin theta = y / r the angle at the bottom is (90 - 32) = 58 sin 58 = 20 / r r = 20 / sin 58 = 23.583568067241928552025478405751 feet ladder must be about (rounding) 23.6 feet long.
What is the square footage of a triangle 20 foot long a 6 foot 3 in high?
20ft X 6.25ft = 62.5 ft2
What is the minimum length of a ladder required to access a roof surface 12 feet off the ground?
You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.
