The area will be the area of the rectangular part, plus the area of the semicircular part.
\n" ); document.write( "
\n" ); document.write( "For the second part:
\n" ); document.write( "If the radius is \"2\"ft, the diameter, which is also the width of the rectangle, is
\n" ); document.write( "\"2%2A2ft=4\"ft.
\n" ); document.write( "That would be the base of the downwind.
\n" ); document.write( "and if the height of the rectangular part is twice the base, then that height is
\n" ); document.write( "\"2%2A4\"feet=\"8\"feet.
\n" ); document.write( "Then the area of the rectangular part is \"%284ft%29%288ft%29=32ft%5E2\"
\n" ); document.write( "The area of half of a circle with radius \"2ft\" is
\n" ); document.write( "\"%281%2F2%29pi%2A2%5E2ft%5E2=%281%2F2%294pi\"\"ft%5E2=2pi\"\"ft%5E2\"
\n" ); document.write( "The total area is
\n" ); document.write( "\"32ft%5E2%2B2pi\"\"ft%5E2=highlight%28%2832%2B2pi%29%29\"\"ft%5E2\"= approximately\"%2832%2B6.28%29ft%5E2=highlight%2838.28%29ft%5E2\" .
\n" ); document.write( "
\n" ); document.write( "For the first part, a rectangle 3 feet by 6 feet would have an area of 72 square feet, and a semicircle with a 6 feet diameter (3 feet radius) would have an area of
\n" ); document.write( "\"%281%2F2%29pi%2A3%5E2ft%5E2=%289%2F2%29pi\"\"ft%5E2\"=approximately \"14.14ft%5E2\",
\n" ); document.write( "for a total area of approximately \"86.14ft%5E2\".
\n" ); document.write( "That is what you found, aside from the rounding difference.
\n" ); document.write( "(I used a more accurate version of \"pi\", but I would get 86.13 too, If I used 3.14 por \"pi\").
