The formula for the area of a square with sides of length x is A = x2 so
x2 = 400 is the equation
This equation has 2 solutions, namely x = ±√400 = +20 or -20
The negative solution does not make sense because a length cannot be less than 0.
The total length needed to go around the painting is the perimeter of the square, which is
P = 4*x = 4*20 = 80 inches

You start by putting the numbers up and down like this
56
x 31
--1------
1 56
1580
---------
1736
On top of the 5 at the bottom you put 2 ones on top because 5+8 is 13 hope this helps
