Given PRQ is a triangle.
ST is a line parallel to RQ.
<u>Triangle proportionality theorem,</u>
<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>
Do cross multiplication, we get
Divide by 2x on both sides, we get
We need the perimeter of the window for framing
The window is in the shape of a rectangle with the height of
feet and width of 
. The diagram of the shape is shown below
The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.
The perimeter of the window is
= 
We have two whole numbers 18 and 12 and two fractions
and 
Adding the two fractions that have different denominator
, which is an improper fraction which we can change into a mixed number 
So the perimeter of the window is
and the length of wood needed for the frame is
