Question

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

Explanation:

Step1: Find hypotenuse using Pythagorean theorem

Let \(a = 60\) and \(b=80\). By \(c=\sqrt{a^{2}+b^{2}}\), we have \(c=\sqrt{60^{2}+80^{2}}=\sqrt{3600 + 6400}=\sqrt{10000}=100\).

Step2: Calculate perimeter

Perimeter \(P=a + b + c\). Substitute \(a = 60\), \(b = 80\) and \(c = 100\), so \(P=60+80 + 100=240\).

Answer:

240
