Math Help with earth stuff

Hi Haley,

Area is the number of squares that fit inside a 2dimensional shape.

Here is a pink peice of paper.  Each one of those little squares is 1cm by 1cm  which means each one is $$1cm^2$$

Now you can count the squares - There are 36 of them so the Area must be $$36cm^2$$

Now how can we get this just with the length of the sides?

There are 12 squares in the top row. And there are 3 rows. So that must be 12+12+12 squares altogether.

or more simply   $$12\times 3 =36cm^2$$

So the area of a rectangle is length x breadth and the answer will be in units squared     $$u^2$$

Usually, standard printer paper is 8.5 X 11 in.

So, the length is 8.5 in. and the width is 11 in.

Area is L X W = 8.5 X 11 in. = 93.5 in.^2.
