Hi there,
\n" ); document.write( "Imagine you have a right angled triangle.
\n" ); document.write( "Width = 20 meters
\n" ); document.write( "Length = x
\n" ); document.write( "Diagonal = x + 5
\n" ); document.write( "(20)^2 + (x)^2 = (x + 5)^2
\n" ); document.write( "400 + x^2 = x^2 + 10x + 25
\n" ); document.write( "Collect like terms.
\n" ); document.write( "10x = 400 - 25
\n" ); document.write( "10x = 375
\n" ); document.write( "x = 37.5 meters
\n" ); document.write( "Length of parcel = 37.5 meters.
\n" ); document.write( "Hope this helps :-)
