Paul [167]

Answer:

They're 241 feet apart

Step-by-step explanation:

we know that

To find out the distance from opposite corners of a rectangle, apply the Pythagoras Theorem

we have

$c^{2}=a^{2}+b^{2}$

where

c is the distance from opposite corners of a rectangle

a and b are the length and the width of rectangle

substitute the given values

$c^{2}=120^{2}+209^{2}$

$c^{2}=58,081$

$c=241\ ft$

therefore

They're 241 feet apart
