let length of painting = L and width = W
\n" ); document.write( "from area = length x width
\n" ); document.write( "180 inch^2 = L x W
\n" ); document.write( "but L = 5/4 x W
\n" ); document.write( "180 inch^2 = 5/4 x W x W
\n" ); document.write( "W^2 = (4 x 180)/5
\n" ); document.write( "W = 12
\n" ); document.write( "but L = 5/4 x W
\n" ); document.write( "L = 5/4 x 12
\n" ); document.write( "L = 15
\n" ); document.write( "hence the dimensions are 15 inches long and 12 inches wide
\n" ); document.write( "
\n" );
