Pythagorean Theorem
c² = a² + b²
c² = √(3)² + (5)²
c² = √9 + 25
c² = √34
c = 5.830951895 units
The answer is 5.83 Units rounded to two decimal places.

Perimeter
= 3 + 5 + â(3² + 5²)
= 8 + â34
= 8 + 5.831
= 13.831 units

the 3rd side is sqrt of 3^2 + 5^2 = sqrt 9 + 25 = 6
So, the perimeter is 3 + 5 + 6
