A piece of wire is in the shape of an equilateral triangle with side 80 cm.
\n" ); document.write( "3 * 80 = 240cm, the total length of the wire
\n" ); document.write( ";
\n" ); document.write( " The wire is reshaped into a rectangle in which the length is twice the width.
\n" ); document.write( "let x = the width
\n" ); document.write( "then
\n" ); document.write( "2x = the length
\n" ); document.write( "Find the x using a perimeter of 80 cm
\n" ); document.write( "2(2x) + 2x = 80
\n" ); document.write( "6x = 80
\n" ); document.write( "x = 80/6
\n" ); document.write( "x = 13\"1%2F3\" = the width
\n" ); document.write( "then
\n" ); document.write( "2(13\"1%2F3\") = 26\"2%2F3\" cm is the length
\n" ); document.write( ":
\n" ); document.write( "A = 26\"2%2F3\" * 13\"1%2F3\" = 355.555 sq/cm is the area of the rectangle
\n" ); document.write( ":
\n" ); document.write( " calculate the area of the rectangle in square metres
\n" ); document.write( "\"355.556%2F100%5E2\" = .0355555 sq/m
\n" ); document.write( "
\n" );
