Many people use ladders, like firemen, construction workers, and your average American.
A Ladder.
When a person climbs a ladder, his muscles provide the energy (work) to raise the person's weight from the ground to the top of the ladder. When the person climbs a ladder carrying a load in addition to his body, his muscles provide the energy (work) to raise his weight from the ground to the top of the ladder, plus the additional energy (work) to raise the load from the ground to the top of the ladder. The more weight goes up the ladder, the more work is done. Of that you can be positive.
You could use "ladder" in a sentence like this... I climbed up the ladder to get in my attic. My dad owns a ladder. We keep our ladder in our backyard. I climbed up the ladder. Do you own a ladder?
You work as a house painter. When you set up your ladder, you like to set the base 5-ft from the wall, for stability. How high on the wall can you reach with a 12-ft ladder ? With a 15-ft ladder ? With a 30-ft ladder ? ============================================================== The question is not: Can the Pythagorean Theorem help you in real life ? The question is: Is your life real enough yet that you can use the Pythagorean Theorem to make it easier ?

The main purpose of a ladder is to allow people to get higher than they can reach. A ladder works by leaning it up against a solid surface and then the person climbs the ladder using the rungs.
You can use a step ladder for multiple purposes. For ex. you can use it to clean the ceiling or the fans. This ladder can help reach to the far off objects in the store room.
