Step-by-step explanation:
To complete the square, we first have to get our equation into form.
First we add 16x to both sides:
And now we subtract 62 from both sides.
We now have to add to both sides of the equation. b is 16, so this value becomes
.
We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because and
.
We can now take the square root of both sides.
We can now isolate x on one side by subtracting 8 from both sides.
So our solutions are

Find the area of the rectangle. You can find the area of a rectangle with the following formula:
w = width, and l = length.
Plug in your width and length:
The area of the rectangle is 200 square centimeters.
The area of a square is also given by width * length. Multiply the sides together:
The area of a square is 4x^2.
Because you're cutting away the square from the rectangle, you will subtract the area of the square from the area of the rectangle. The following equation will be your answer:
w = width, and l = length.
