The squares on a chess board are not usually numbered, however the board is 8 squares wide and 8 squares long, giving 64 squares in total.

Rectangles are quadrangles, polygons with four sides. A rectangle is a quadrangle with two long sides and two short sides, and the long sides and short sides are parallel to each other. They are parallelograms, in which opposite sides are parallel. Note: All squares are also rectangles.
80 squares is a measure of area, it doesn't apply to length.
In order to make three squares the same size with four long straws and four short straws make a ladder with the straws. Place the long straws at the side the short ones are the rungs.
<X X> It should look kinda like the example above. Except it would be squares lol. Make two crosses with the 4 long straws put the ends of these together so that one square is made then make two right angles with the four short straws and place them at the other side of each cross to make three squares in a diagonal line. :)
first put two long ones at the top and at the bottom.then put 1 short one on each side.the two left overs you put in the middle.

There are 6C2 = 6*5/(2*1) = 15 pairs.
straws
Depends how long each straw is. Straws come in different lengths. A way to find out is using the equation 1000000x=y Where x = the length of each straw and y = the total length of the straws end to end.
There are 48 such squares.
6... with a remainder of 6 1x1 squares.

This shape is going to be a rectangle. Picture a rectangle that is twice a long as it is wide. Now draw a line segment to exactly bisect the long side. You now have two congruent squares sitting side by side.
