Question

This rectangular prism is intersected by a plane that contains points N, P, U, and R.

Answer 1

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 $PU^{2}= 6^{2}+15^{2}$

$PU^{2}=36+225$ = 261 feet

$PU=\sqrt{261}$ =16.155 feet

So, the perimeter will be $2(6+16.155)$ = 44.31 feet

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

Answer 2

The answer is 44.3 ft.
