The problem description is somewhat ambiguous. Width of the window is 7.500 feet; but is THE semicircle attached to a width or is it attached to a length? Any figure or diagram included in your book or page might help tell you this nonverbally.

I can explain generally.

x and y are the dimensions of the rectangle portion of the window. You know perimeter of the window p and one of the diensions, either x or y;
but you do not know A area of the window.

p=36.9000
A is unknown
either x or y is known but not both.

Either x or y serves as diameter of the semicricle, but only one of those dimensions; NOT both, and not both at the same time.

If the semicircle has diameter of y, then , and .

Nothing more specific without the exact and complete problem description.
