1) 7² - 6² = 49 - 36 = 13
 
In short, We need 13  blocks to add to square 6 to get 7

2) 10² - 9² = 100 - 81 = 19

In short, We need 19 blocks to add to square 9 to get 10

3) 20² - 19² = 400 - 361 = 39

In short, We need 39 blocks to add to square 19 to get 20

Hope this helps!

A square has an area of 289 sq cm. what is the length of one side
MatroZZZ [7]
For this problem you can do it one of two ways. The first way would be simply take the square root because the area of a square is one side squared. The other way using the same rule would be to go up from a reasonable number and square it, if that is not the number you are looking for add 1 to the original number and square it again. if you cannot square and square root in your head, you should be allowed to use a calculator to get the answer or 17 as the length of a side.
