Question

what is the perimeter? if necessary, round to the nearest tenth. miles

Explanation:

Step1: Find hypotenuse c using Pythagorean theorem

By $c=\sqrt{a^{2}+b^{2}}$, where $a = 48$ and $b = 55$. So $c=\sqrt{48^{2}+55^{2}}=\sqrt{2304 + 3025}=\sqrt{5329}=73$

Step2: Calculate perimeter

Perimeter $P=a + b + c$, substituting $a = 48$, $b = 55$, $c = 73$, we get $P=48+55 + 73=176$

Answer:

176
