We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.
SO the length of rectangular window is
feet.
Width of the rectangular window is =
feet.
In general parameter of rectangle is =
So the parameter of window is =
So the required length of wood to frame window is = 28.834 feet

Euclid's fifth postulate states, rather wordily, that:
<em>if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, </em><span><em>the two straight lines, if produced indefinitely, meet on that side </em><em>on</em><em> which are the angles less than the two right angles.
</em></span>
<em />If that sounds like a mouthful to you, you're not alone. Geometers throughout history found that postulate incredibly awkwardly-worded compared with his other four, and many in the 19th century rejected it outright and created a number of interesting new geometries from its ashes.
Euclid's fifth, put another way, states that two lines that aren't parallel will eventually meet, which consequently implies that <em>two parallel lines will never meet</em>. Without intending it, this property defines the space of Euclid's geometry to be <em>an infinite flat plane</em>.
If we take that parallel postulate and throw it out<em>, </em>then we've defined a <em>spherical space</em> for our geometry. Now, it doesn't matter where we draw our lines; <em>all of them will meet at some point</em>. If you need any convincing of this, take a look at the attached image. The longitude lines <em>seem </em>parallel at first, but they all eventually meet at the north and south poles.
