You can put this solution on YOUR website!
For a rectangle, Area = length * breadth
\n" ); document.write( "Perimeter = 2(length + breadth)\r
\n" ); document.write( "\n" ); document.write( "Let l rep. length, breadth reo. w
\n" ); document.write( "From statement Area, l*w=18.86 eqn1
\n" ); document.write( "and Perimeter, 2(l+w)=21
\n" ); document.write( "expanding
\n" ); document.write( "2*l+2*w=21 ----eqn2
\n" ); document.write( "Solving eqn1 and eqn2 simultaneously\r
\n" ); document.write( "\n" ); document.write( "\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "\n" ); document.write( "
