Answer: 16.325 in
Step-by-step explanation:
First, we will find b. We will use the Pythagorean theorem to do this.
a² + b² = c²
3² + b² = 7²
9 + c² = 49
c² = 40
c = [tex]\sqrt{40}[/tex] ≈ 6.324555 ≈ 6.325 in
Now, we will add all the sides together to find the perimeter.
3 in + 7 in + 6.325 in = 16.325 in
