Let's say the length of the ladder is "d". Since the distance from the bottom of the ladder to the building is 16 feet less than the length, we can write this as d - 16.
The distance from the ground to the top of the ladder is 2 feet less than the length of the ladder, so we can denote this as
d - 2.
The shape made by the ground, ladder, and side of the building is a right triangle, and we just found its legs. We can use the Pythagorean Theorem to solve for "d" and find how far up the side of the building the ladder is:
(d - 16)^2 + (d - 2)^2 = d^2
(d^2 - 32d + 256) + (d^2 - 4d + 4) = d^2
2d^2 - 36d + 260 = d^2
d^2 - 36d + 260 = 0
(d - 26) * (d - 10) = 0
d = 26 or d = 10
The answer d = 10 does not fit in this case because it isn't possible to have 16 feet less of 10 feet; it would be negative!
So, d = 26. The top of the ladder to the ground is 2 less than d, so we do 26 - 2 = 24 feet.
The answer is 24 feet.
Girl thats so easy i can help you
The long piece of the board is 100 cm and the shorter board is 20. you can solve this by dividing 120 by 6 since u need to have a piece that is 5x a piece which is a total of 6 pieces. Then multiply that number by 5 and that is your longest board.

Answer:
96 square meters
Step-by-step explanation:
Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.
We then find the area of one face which is 4 * 4 = 16 square meters.
We must then multiply this by the amount of sides on our cube which is 6.
16 * 6 = 96 square meters.
