Give this a try


<HTML>
<HEAD>
<TITLE>test</TITLE>

<SCRIPT type="text/javascript">

var shapeArray = new Array (4);
var RectangleLength;
var RectangleWidth;
var sum1;
var sum2;
var circle;

function test(){

for (var i= 0; i< shapeArray.length; i++){

shape=window.prompt('Please enter shape "r" for rectangle or "c" for Circle');

if(shape=='r'){

RectangleLength = window.prompt('Please enter the length of the rectangle in centimetres','');
RectangleLength=parseFloat(RectangleLength);

RectangleWidth = window.prompt('Please enter the width of the rectangle in centimetres','');
RectangleWidth=parseFloat(RectangleWidth);

shapeArray[i]='The area of the '+shape+' is ' +RectangleLength * RectangleWidth+ ' square centimetres <br>'

}

if (shape=='c'){
circle = window.prompt('Please enter the radius in centimetres','');
circle=parseFloat(circle);

shapeArray[i]='The radius of the circle is '+circle * circle * 3.142+'<br>'

}

document.getElementById("display").innerHTML+=shapeArray[i]

}

}

You could use toFixed(2) for 2 decimal places

Change this line

shapeArray[i]='The area of the '+shape+' is ' +RectangleLength * RectangleWidth+ ' square centimetres <br>'

to

shapeArray[i]='The area of the '+shape+' is ' +(RectangleLength * RectangleWidth).toFixed(2)+ ' square centimetres <br>'

and this line

shapeArray[i]='The radius of the circle is '+circle * circle * 3.142+'<br>'

to

shapeArray[i]='The radius of the circle is '+(circle * circle * 3.142).toFixed(2)+'<br>'

My previous reply does the same thing but if you'd prefer the function then

Change this line

shapeArray[i]='The area of the '+shape+' is ' +RectangleLength * RectangleWidth+ ' square centimetres <br>'

to

shapeArray[i]='The area of the '+shape+' is ' +roundToTwoPlaces(RectangleLength * RectangleWidth)+ ' square centimetres <br>'

and this line

shapeArray[i]='The radius of the circle is '+circle * circle * 3.142+'<br>'

to

shapeArray[i]='The radius of the circle is '+roundToTwoPlaces(circle * circle * 3.142)+'<br>'


and put the new function at the end of the script
