It is given that x is 5 less than the quotient of y and 3.
And given value of y is 18 .
So quotient of y and 3 is
And 5 less than 6 =1
So we have y=18 and x=1
Given expression is
At x=1 and y=18, we will get

we know that
The circumference of a semicircle (window) is equal to
we have that
substitute and solve for r
so
the width of the window is equal to the diameter of the semicircle
so
The width of the window should be and the height of the window should be
