a window has the shape of a rectangle with a half circle on top.
\n" ); document.write( " the rectangle has a width of 3 feet and a height of 7 feet.
\n" ); document.write( " find the perimeter and the area of the window. use pi=3.14 where necessary.
\n" ); document.write( ":
\n" ); document.write( "The width of the window will be the diameter of the half circle
\n" ); document.write( "therefore half the circumference = \"1%2F2\"*3.14*3 = 4.71 ft
\n" ); document.write( "Perimeter = 2(7) + 3 + 4.71 = 21.71 ft
\n" ); document.write( ":
\n" ); document.write( "The area (r = 1.5)
\n" ); document.write( "Area of the half circle = \"1%2F2\"*3.14*1.5^2 = 3.5325
\n" ); document.write( "Area of the rectangle = 7 * 3 = 21
\n" ); document.write( "total area; 3.5325 + 21 = 24.5325 sq/ft\r
\n" ); document.write( "\n" ); document.write( ":
\n" ); document.write( " \n" ); document.write( "
