You can put this solution on YOUR website!
A rectangle has 2 lengths and 2 width
\n" ); document.write( "Starting from the area, we can find the missing dimensions, the formula in find area of rectangle is length* width.
\n" ); document.write( "plug numbers you have to formula.
\n" ); document.write( "36m^2=4m*x ==> let x be how long width is
\n" ); document.write( "simplify: 36=4x divide four on both sides
\n" ); document.write( "length of width is 9m
\n" ); document.write( "now you have the dimensions of the rectangle: width=9m length=4m
\n" ); document.write( "from here find the perimeter by adding the sides together.
\n" ); document.write( "there are 2 lengths and 2 with in a rectangle so the formula for perimeter:
\n" ); document.write( "P= w+w+l+l or simply P=2w+2L
\n" ); document.write( "plug into formula (either one)
\n" ); document.write( "P=9+9+4+4 or P=2(9)+2(4)
\n" ); document.write( "P=26m =======P= 26m either formula should get you the same answer.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: perimeter of rectangle is 26m the missing side was 9m \n" ); document.write( "

\n" );
