Find the dimensions of a rectangular field that has a perimeter of 724m and an area of 32400m^2.
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Perimeter = 2(length + width)
\n" ); document.write( "724 = 2(length + width)
\n" ); document.write( "length + width = 362
\n" ); document.write( "--------------------------
\n" ); document.write( "length * width = 32400
\n" ); document.write( "================================
\n" ); document.write( "EQUATIONS:
\n" ); document.write( "l = 362-w
\n" ); document.write( "Substitute to solve for width:
\n" ); document.write( "(362 -w)w = 32400
\n" ); document.write( "-w^2+362w-32400
\n" ); document.write( "w^2-362w+32400 = 0
\n" ); document.write( "w = [362 +- sqrt(1444)]/2
\n" ); document.write( "w = [362 +- 38]/2
\n" ); document.write( "w = 200 (width)
\n" ); document.write( "---------------
\n" ); document.write( "Solve for length:
\n" ); document.write( "l + 200 = 362
\n" ); document.write( "l = 162 (length)
\n" ); document.write( "=================================
