Step-by-step explanation:
This diagonal creates a right triangle with one leg 14m and another leg 22 m. We can use pythagorean theorem to figure out the diagonal (hypotenuse of the right triangle).
Pythagorean theorem tells us
The fence needs to be 26.08 meters (rounded to 2 decimal places)

Answer:
Each senior citizen ticket costs $7 and each child ticket costs $5.
Step-by-step explanation:
Let,
x be the price of each senior citizen ticket
y be the price of each child ticket
According to given statement,
x+4y=27 Eqn 1
6x+8y=82 Eqn 2
Multiplying Eqn 1 by 2
2(x+4y=27)
2x+8y=54 Eqn 3
Subtracting Eqn 3 from Eqn 2
(6x+8y)-(2x+8y)=82-54
6x+8y-2x-8y=28
4x=28
Dividing both sides by 4
Putting x=7 in Eqn 1
7+4y=27
4y=27-7
4y=20
Dividing both sides by 4
Hence,
Each senior citizen ticket costs $7 and each child ticket costs $5.
