Question 333419: If I have a white board that is 80 cm by 120cm, then the total surface are would be 9600 cm2. However, my problem is that I want to divide the board into 45 even squares..So this is where I am stuck... Answer by Mathematicians(84) (Show Source):
You can put this solution on YOUR website! We know that the surface area of the entire board is 9600 cm^2.
If we want to divide that up into 45 equal squares, you would want to see what the area of each square has to be:
So the area of each square has to be 640 / 3.
We know the area for any rectangle is , however, for a square we know that b = h, so we get
Finally, combining it with our last example, we get:
=> =>
Since we are working with distance, we would take the positive answer.
