A small city park consists of a rectangular lawn surrounded on all sides by a 330m sq. border of flowers 2.5m wide. Find the area of the lawn if the entire park is 5m longer than it is wide.
\n" ); document.write( ":
\n" ); document.write( "I assume they mean the area of the border is 330 sq ft
\n" ); document.write( ":
\n" ); document.write( "Let x = length of the park; (x-5) = the width of the park
\n" ); document.write( ":
\n" ); document.write( "Divide the walkway into 4 narrow rectangles:
\n" ); document.write( "2 ea: (x - 2.5) by 2.5
\n" ); document.write( "2 ea: (x - 7.5) by 2.5
\n" ); document.write( ":
\n" ); document.write( "The area equation:
\n" ); document.write( "2[(x-2.5)*2.5] + 2[(x-7.5)*2.5] = 330
\n" ); document.write( "2(2.5x - 6.25) + 2(2.5x - 18.75) = 330
\n" ); document.write( "5x - 12.5 + 5x - 37.5 = 330
\n" ); document.write( "10x - 50 = 330
\n" ); document.write( "10x = 330 + 50
\n" ); document.write( "10x = 380
\n" ); document.write( "x = 38 ft is the length, the width = 33 ft
\n" ); document.write( ":
\n" ); document.write( "Find the area of the entire park: 38*33 = 1254 sq ft.
\n" ); document.write( "Area of the lawn = 1254 - 330 = 924 sq ft.
\n" ); document.write( ":
\n" ); document.write( "Check it by finding the dimensions of the lawn and finding the area from that:
\n" ); document.write( "Lawn dimensions: (38-5) by (33-5): 33 * 28 = 924 sq ft also \n" ); document.write( "
\n" );
