// This line makes the button, btnCalculate wait for a mouse click
// When the button is clicked, the displayRectangleProperties function is called
btnCalculate.addEventListener(MouseEvent.CLICK, displayRectangleProperties);

// This is the displayRectangleProperties function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function displayRectangleProperties(e:MouseEvent):void
{
    // declare the variables
    var length:Number;
    var width:Number;
    var area:Number;
    var perimeter:Number;

   // calculate the area and perimeter of a square
    length = 30
    width = 35
    area = length * width;
    perimeter = length + width + length + width;

    // put the values into the labels
    lblLength.text = length.toString();
    lblWidth.text= width. toString() ;
    lblArea.text = area.toString();
    lblPerimeter.text = perimeter.toString();
