According to the Pythagorean theorem procedure, it can be inferred that the missing side is equal to 7.48m and the perimeter of the pool is 35.5m.
How to calculate the length of the missing side?
To calculate the length of the missing side we must perform the following mathematical procedure using the Pythagorean theorem:
- x² = 15² - 13²
- x² = 225 - 169
- x² = 56
- x = √56
- x = 7.48m
On the other hand, to calculate the amount of fence needed for the pool, we add all the sides and we will know the length of the perimeter, that is, the fence needed as shown below:
- 15 + 13 + 7.48
- 35.48m = 35.5m
