what is the perimeter? if necessary, round to the nearest tenth. centimeters
Answer
Answer:
48.0
Explanation:
Step1: Find the hypotenuse c
Use Pythagorean theorem $c=\sqrt{12^{2}+16^{2}}$. $c=\sqrt{144 + 256}=\sqrt{400}=20$.
Step2: Calculate the perimeter
Perimeter $P=12 + 16+20$. $P = 48$. Since no rounding is actually needed for an integer result, we can write it as 48.0 to one - decimal place as per the requirement.
