You can put this solution on YOUR website!
p = perimeter of the rectangle.
\n" ); document.write( "x = the length
\n" ); document.write( "y = the width.
\n" ); document.write( "p = 2 * (x + y)
\n" ); document.write( "that means the perimeters is equal to 2 times the sum of the length and the width.
\n" ); document.write( "x = 30m
\n" ); document.write( "y = 15m
\n" ); document.write( "p = 2 * 45m = 90m
\n" ); document.write( "here's a reference on perimeter of a rectangle.
\n" ); document.write( "https://www.varsitytutors.com/basic_geometry-help/how-to-find-the-perimeter-of-a-rectangle
\n" ); document.write( "the references uses l for the length and w for the width.
\n" ); document.write( "my formula would then be:
\n" ); document.write( "p = perimeter of the rectangle
\n" ); document.write( "l = length
\n" ); document.write( "w = width
\n" ); document.write( "p = 2 * (l + w)
\n" ); document.write( "this is the same as p = 2l + 2w.
\n" ); document.write( "i just factored out the 2.\r
