Basically she has two half circles and and on circle at the centre\r
\n" ); document.write( "\n" ); document.write( "which means 2 full circles\r
\n" ); document.write( "\n" ); document.write( "The diameter of the circles will be the width of the plot which is 10 feet\r
\n" ); document.write( "\n" ); document.write( "so radius of the circles will be 5 ft\r
\n" ); document.write( "\n" ); document.write( "Area of circle = pir^2\r
\n" ); document.write( "\n" ); document.write( "= pi * 5^2
\n" ); document.write( "= 25 pi\r
\n" ); document.write( "\n" ); document.write( "two circles
\n" ); document.write( "so 50 pi is the area of the garden
\n" ); document.write( "=157 sq.ft\r
\n" ); document.write( "\n" ); document.write( "area of rectangle = 20 * 10 = 300 sq.ft\r
\n" ); document.write( "\n" ); document.write( "area to be covered with chips = 200 -157= 43 sq. ft\r
\n" ); document.write( "\n" ); document.write( "5 sq. ft ----------1 bag
\n" ); document.write( "43 sq. ft ----------- 43/5 = 8.6 bags\r
\n" ); document.write( "\n" ); document.write( "= 9 bags\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
