\n" ); document.write( "\n" ); document.write( "5) The ratio of area and perimeter of a square is 2 : 1 , then area of circle with diameter equal to diagonal of square is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let the measure of the side of the square be represented by

.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then the Area is given by

and the perimeter by

. But with the given proportion,

. Hence

which is to say

.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The diagonal of a square with side measure

, hence the radius of a circle with diameter equal to the diagonal of the square is

, in your case,
