what is the perimeter? if necessary, round to the nearest tenth. kilometers
Answer
Explanation:
Step1: Find the hypotenuse c using Pythagorean theorem
By the Pythagorean theorem $c=\sqrt{a^{2}+b^{2}}$, where $a = 15$ and $b = 36$. So $c=\sqrt{15^{2}+36^{2}}=\sqrt{225 + 1296}=\sqrt{1521}=39$.
Step2: Calculate the perimeter P
The perimeter of a triangle is $P=a + b + c$. Substitute $a = 15$, $b = 36$ and $c = 39$ into the formula. So $P=15+36 + 39=90$.
Answer:
90
