Answer:
Step-by-step explanation:
All side lengths of a square are equal. The three squares create a right triangle, and the hypotenuse of this triangle represents the side length of the square.
All right triangles must follow the Pythagorean Theorem 
where 
is the hypotenuse of the triangle.
Therefore, let 
be the side length of this largest square. Since the area of a square with side length 
is given by 
, 
will represent the area of the square:
0.08*x+0.03*(29000-x)<span> </span>
X=2
subtract 5x on both sides
-2x=-4
divide by -1 on both sides
2x=4
divide by 2 on both sides
x= 2
