Answer:

Step-by-step explanation:

Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2

When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.

The answer to b is the same. The width =7

It's a square both sides have to be equal.  

The length of the rectangle when the two squares are put together is 7 +7 = 14.

Answer: Question a = 7..... Question b = 7 ......... Question C = 14
