The answer is 44.3 ft.

Answer:

The perimeter is : 44.3 ft

Step-by-step explanation:

Two of the parallel sides ST and NP of the plane will each equal = 6  feet

Side PU will be [tex]PU^{2}= 6^{2}+15^{2}[/tex]

[tex]PU^{2}=36+225[/tex] = 261 feet

[tex]PU=\sqrt{261}[/tex] =16.155 feet

So, the perimeter will be [tex]2(6+16.155)[/tex] = 44.31 feet

Rounding this final answer to the nearest tenth we get 44.3 feet.
