Area of a Rectangle

                                                                                                                         

To find the area of a rectangle you have to know the formula.

The formula l x w = a    l = length w = width a= area                                            

 

 You have to know this if you have a problem like this,' What is the area of a rectangle'.

3 in

                                                        7 in

                                                                                                                          

All you have to do is 3 x 7 = 21 squared  

So your answer is 21 inches squared.

On all rectangles, when you find the area you have to square it.
