Since the radius is 2.5, the diameter is 5.
\n" ); document.write( "A diagonal for the rectangle is equal to this diameter.
\n" ); document.write( "We have a triangle with side lengths of 5 and 4.
\n" ); document.write( "5 is the hypotenuse. Set x = the length of the
\n" ); document.write( "other side of the triangle.
\n" ); document.write( "So \"4%5E2+%2B+x%5E2+=+5%5E2\"
\n" ); document.write( "\"16+%2B+x%5E2+=+25\"
\n" ); document.write( "add -16 to each side
\n" ); document.write( "\"x%5E2+=+9\"
\n" ); document.write( "x = 3
\n" ); document.write( "We have side lengths of 3 and 4 so
\n" ); document.write( "the area = 3*4 = 12
\n" ); document.write( "
\n" );
